AJAX HTTP error 200

Me too me it's the same with the discharge of language.
So this one trnho installed nothing else besides Drupal 7.0, Locale updater7.x-1.0-alpha1 and locale-1.0-dev updater7.x
Attached image transmission.

I'm going to call this a Drupal for Firebug problem then....

With drupal for firebug & preprocessor enabled, I also get a similar error (result code 200) when I try to edit configuration options for my content fields (i.e. when I press the gears icon when I add an image field to a content type)
Also got errors when I tried uploading files.
I also got a different ajax error "NPMethod called on non- NPObject", which I haven't been getting after I disabled the module, so I'm assuming it also had to do with an issue with the firebug module.

All errors stopped after I disabled the modules.
Hope this may help in debugging the problem.

Thanks for all the hard work

This is very bad thing

Oh, now we go with drupal_get_HTTP_headers(), not drupal_get_headers()...

Patch is attached

I was running into the same issue when trying to manage display of fields within my content types. It doesn't seem to be content type specific. Any attempt to change the display of fields within a content type initiated this error and when I tried to save changes, nothing was changed. My site was at a standstill and then I tried disabling Firebug for Drupal and I was able to proceed.

Found similar info with a devel bug but I did not have that module installed: http://drupal.org/node/699668

@sammyframson

Have you tried the patch?

I have manually installed the patch and no longer get the AJAX error, thanks for the help.

I had the same ajax issue when trying to fill autocomplete fields or in views with drupalforfirebug activated. patch in #6 worked. thx.

as of #10 and the dup: #1040392: [THIS ISSUE IS CLOSED - DO NOT COMMENT]An AJAX HTTP error occurred. HTTP Result Code: 200 FIXED
setting to tested and praying to maintainers

Thanks for checking into this and this has been now been committed to the repository.

Seems the bug is back. I've tested it with the latest dev versions of this module and Panels on my local host. Tested in a vanilla setup.

I get the error when trying to add any of the Selection rules in a Variant:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: http://localhost:8082/ctools/context/ajax/access/add/page_manager_task_handler-node_view%2Anode_view_panel_context/php

Turning this module off and Panels work.

Attached is a txt with all the gooblygook in the ResponseText if anybody is interested.

I don't know how to apply or set up the patch.Can you tell me the details?

Here is a pretty good, easy to follow article on applying patches... http://bri-space.com/content/how-patch-drupal-module-windows

I had echo statements, print statements from a code I imported into a module..

Removing them fixed it.

I am marking this as a duplicate because the issue as it was is fixed. The panels specific fix is being discussed in a different thread.

Drupal For Firebug Breaks Panels

I have the same problem for this 2 days. I haven't got any drupal for firebug, any devel module, no errors with the MySQL max_allowed_packet and no errors even with max_execution_time of php.ini. The problem was a damn character before a "<?php" in one custom module. I think it's because the text editor... I delete the '^R' character and all works fine.

I found it by disabling modules one by one and executing the "check for updates" script in /admin/reports/updates/check. When I disabled this wrong module and the script runs... THE ERROR WAS HERE!!!

I'll show you my code and the damn hidden character. I hope it helps...

^R<?php

/**

/**

function redif_suscription_menu() {
  $items['admin/config/system/redif'] = array(

Anyone having lots of AJAX issues might want to try disabling the jquery_update module, worked for me. Just spreading the info, unsure if it's related to this issue.

deanflory, if you are having an issue with compatibility with jquery_update and drupalforfirebug then please let us know what version of drupal, drupalforfirebug, and jquery_update that you are using.

If the problem persists please open a new issue.

And thanks for the info. :)

#24, Thanks @deanflory, this worked me, too.

However, since I need this module, I didn't disable completely but downgraded the jQuery Version from 1.8 to 1.7. I think there's something wrong with jQuery 1.8 when it comes to work with Drupal.

Yes, There is an issue for this in the jquery_update module. it seems not so much to be with Drupal and jQuery1.8 as much as jQuery 1.8 and jQuery UI.

I concur with #26 this solution does work....there seems to be an issue with version 1.8

I've run out of ideas where to look for this solution. I've searched endlessly all ajax errors I can find, none are specific to this form that I've located and none are specific to the modules involved.

It first started using Location with GMap. I contacted the maintainer and posted there about how the ajax autocomplete would never complete, so the form would always be submitted prior to ajax finishing and return a fatal error. After weeks of searching and reporting back for help, no luck. After uninstalling those modules, I installed Leaflet 7.x-1.0 beta2, its library (Leaflet v0.5.1-0), GeoCoder 7.x-1.2, Geofield 7.x-1.1, Geophp 7.x-1.7 and now when I add the geofield field to the content type via manage fields and click on format settings for Leaflet and save it (with or without making any changes to the settings) I receive the error message below and cannot proceed.

I sincerely apologize if this is NOT where to place this, but I can't tell where it should go...a new issue somewhere? If so, please advise and I'll post there. Too new to Drupal to know all the ins and outs, and appreciate any help in resolving this persistent "ajax error" issue. Thank you.

I am NOT using drupalforfirebug or jquery_update - the two modules everyone is saying need to be disabled...

I am using Drupal 7.4

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /system/ajax
StatusText: OK
ResponseText:
Fatal error: Call to undefined function element_validate_integer_positive() in /home/(my domain)/includes/form.inc on line 1356

This is the code from lines 1352-1357 in includes/form.inc:

// Call any element-specific validators. These must act on the element
// #value data.
elseif (isset($elements['#element_validate'])) {
foreach ($elements['#element_validate'] as $function) {
$function($elements, $form_state, $form_state['complete form']);
}

What is very interesting to me about that error is that the function that is supposed to be called is in the same file, line 4188.

Sorry I cannot be of more help and you're right. This isn't really the place to be asking about this. You should checkout the support forums. You could also checkout one of the #drupal channels on IRC.

Just as a precaution, you said you where new to Drupal, make sure you clear your caches, try in other browsers, use firebug to see if there are other js errors that could be causing this, uninstall all modules that are disabled, try a fresh installation and build the same thing in a vanilla drupal install, do a registry rebuild with the drush rebuild registry module, and before you do anything backup your database.

Welcome to Drupal.

Hey,I resolved that error...you just need to downgrade the jquery version from 1.8 to 1.7 in jQuery Update module

Downgrade jQuery to 1.7
worked for me after loong time of (right click-open in new tab) just to get around it.

Thanks for the thread

Guys, I tried everything, it has been 3 DAYS. I got sick. I argued with my hosting because I thought (or maybe I still think) it was their problem. PLEASE HELP ME.

I'm having this problem: AJAX not working in Manage Display of any content type. I cannot move row or edit configurations on any field, cause ajax won't load the form or move the rows. Still, everything works in Views.

I tried different versions of core, of jquery, patches to jquery, disabling all the modules (also clean urls), disabling features, base_url, rewrite base.. but the possibilities are too many to isolate a single potential problem.

I can't figure out what this is. I was thinking is the hosting provider because it happened when (but I'm not sure) I asked them to change my main domain from one to the second I bought.

I'm getting "Invalid form POST data" at system/ajax.

Drupal core 7.26
Omega 4.1
Shared hosting at public_html, single site

kopeboy, I've had similar/same problems with Display Suite Manage Fields forms not performing correctly. In my case, I was able to move a field from the disabled region to another region and then what I'm guessing is the form's AJAX kicked-in, seemed to perform the operation (could see loading in browser), then the browser would finish loading whatever was being downloaded during the operation but wouldn't then tell the loading animation that it was complete, thus hanging all functionality.

I took two days disabling > testing > disabling > testing modules and found the following were all individually causing errors that prevented the DS Manage Fields forms from working:

• Video Filter
• Calendar Tooltips
• Views Slideshow Configurable Controls
• Views Slideshow: Cycle
• FlexSlider Views Style

I created bug reports in each of these modules (I think), notifying them of the issue as I think it's a pretty big bug/incompatibility when necessary functionality like this is rendered inoperable. I'm in the process of going through issues so we'll see if anything has been resolved or at least acknowledged.

Hopefully this list above will keep others from going crazy (too late).

@kopeboy please don't change the issue status to Needs Review unless you have a patch that needs review. The issue status all mean something.

Active: the problem is Actively being worked on.
Needs Work: The patch that was submitted doesn't work and needs work before being testing again.
Needs Review: A new patch has been submitted and needs to be reviewed

If you are having trouble with the Drupal for Firebug module then please open a new issue.

I had the same issue. its issue with JQuery version 1.8 due to some charachter, it works well with version 1.7.

Amol Yeram

Make sure that you are not using jQuery 1.8

You can see your settings at: /admin/config/development/jquery_update

jQuery 1.5 and 1.7 seem to play well with views. jQuery 1.8 currently does not.

#23 at this post solved the issue for me.

Here at:
https://www.drupal.org/node/1022516#comment-6183024

I had a module file that included non-latin characters. It was encoded using UTF-8 with BOM, I had to change it to UTF-8 without BOM and problem disappeared.

Thanks Ignacio.

Not sure which of the following solved the problem but it works

Disabled og context
Disabled Ajax comment
Changed Jquery to 1.7 in both selection

In fact the #23 above was the most correct. The issue happens not because of something in jQuery Update module and not because of 1.9, 1.10 etc. versions of that lib.
The issue comes from an incorrect encoding of some file in a contrib module.

Solution
You should really search for that module by disabling them one by one and once you find that module convert it to UTF-8 without BOM. Pretty simple huh.

BTW one might ask "why downgrade to 1.7 jQuery helps?"
I don't know. But 1.7 tolerates AJAX responses with an incorrect 1st symbol. 1.8 and beyond - does not.

Everyone should stop posting in this very old issue. This issue was opened 4 years ago in 2011, and closed initially 4 years ago and again 3 years ago.

Please stop posting in this issue.
