Using: http://drupal.org/project/facebook_status

My facebook_status page view (ie. individual user status page view) currently gives "An error occurred at views/ajax" when attempting to switch page. The general status page at facebook_status_recent does not give the same error and works perfectly.

I can't figure out why as they use more or less the same settings.

The only other even slightly similar seeming instance I found of this was a permissions bug here:
http://drupal.org/node/408894

I have ensured permissions are set up and tried changing the access option for the problematic view to 'access content' with no help. I have cleared cache and tried different themes.

Furthermore, if I right click the page link and copy/paste it into my address bar it will load the next page perfectly, so I know it is getting the right links. I just can't click them directly.

Why does AJAX give this error? Any ideas or ways I can debug this?

Thanks.

I checked the error logs and they seem to be registering as 406 page not found. When I try going to the link they are trying to reach I also get Page Not Found.

So for some reason my Ajax is looking for a wrong address on that view. From the link it's requesting below, any idea why or where I should go from here?

(I added WEBSITE to the link above so it would read properly here)

Thanks again.

edit: It appears 406 is typically a server setup issue usually with Apache mod_security. Checking with my host now.

Just for the archives in case someone else has this issue, I contacted my host requesting they disable mod_security.

They replied:

"We have got the following error in the error logs.

=====================
[Tue Aug 18 12:43:32 2009] [error] [client 99.225.189.34] ModSecurity: Access denied with code 406 (phase 2). Pattern match "\%(?![0-9a-fA-F]{2}|u[0-9a-fA-F]{4})" at ARGS:view_base_path.

=====================

To fix this we have disabled that mod sec rule for the URI "/views/ajax". Kindly check now."

It now works perfectly.

I also had this problem on one of my sites, but only in Firefox (IE worked fine for once).
It also happened with the AJAX code from CTools.

A simple fix made it work, insert a space in the data property in all ajaxSubmit calls (views/js/ajax.js). Seems something goes wrong when Firefox tries to POST an empty string.

That host is also running mod_security2, which means it can't be turned off in .htaccess, so you'd have to contact the host like uomeds did.

I'll add my issue here as it's exactly the same: "An error occurred at /views/ajax."

I contacted my webhost and they suggested that I put this code in my .htaccess to prevent the 406 error: 

<IfModule mod_security.c>
# Turn off mod_security filtering.
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

Unfortunately, my error log shows that I'm still getting the 406.

I have ajax working with views and panels in another section of the site and there is no problem there.

The 2 sections where the error occurs is "Slideshow" and "Video" on my front page (Flexible Panel). Those views were built using FeedAPI fields.

When I built this locally on my MAMP environment, everything was fine so it might be a problem with my webhost.

If anyone has encountered a similar issue or has any idea how to fix, please let me know. I'll update with info from the webhost if they find a solution.

Just to give an update, this was the reply from my webhost.

"The modsecurity rule present in the server was blocking the pattern which resulted in the error. Mod_security cannot be disabled globally as the domain residing in a shared environment, so I had to tweak the setting for this domain alone so that the rule could be bypassed.

But please note, disabling mod_security for the domain decreases the level of security of your website. So you can go for a plan upgrade, if needed so that you can tweak the settings as per your wish.

Anyway, this issue should be resolved by now. I request you to check the status from your end after clearing the browser cache and cookies or using a different browser."

Everything is up and running so glad that's fixed. As mentioned in this comment, I'm not too concerned about the mod_security setting being turned off but will report back if there are any bizarre twists.
