Server Error

Check your php.ini settings to ensure the size of the file you are uploading isn't going over the upload/post limits (post_max_size, upload_max_filesize).

The SWFUpload has some debug tools. Change this (line 486 of swfupload.module):

  $settings['swfupload_settings'][$element['#id']] = array(
    'module_path' => $path,

to this:

  $settings['swfupload_settings'][$element['#id']] = array(
    'debug' => TRUE,
    'module_path' => $path,

Any updates on this?

I have some problem? This is my debug message:

I also have found http://www.example.com/swfupload 'access denied' warning in watchdog. But the module is worked successfully on my another local drupal site.

Subscribe, same issue

I'm still unable to get past this problem, does anyone know what would cause this? Thanks

Maybe check out the thread here

http://swfupload.org/forum/generaldiscussion/1125

We are also having this problem and I wonder if it's related to the bug here...

http://drupal.org/node/591142

We are finding the same problem when the site is password-protected via .htaccess. The SWFupload module reports status code 401 and the UI says "Server Error". Removing .htaccess authentication makes it work. Anyone know of a way around this? I've applied the patch in http://drupal.org/node/591142 and also have the swfupload.cookies.js file in our swfupload module directory but are still getting 401 errors when .htaccess password auth is enabled.

I just faced the same problem with SWFupload module where it was working properly on one server and doing exactly opposite on other one. I was getting 403 error as 'server error'.
I searched on google and I found this code to put in .HTACCESS file.
Here is the code:

########## Attempt to solve 'Global Configuration' save issue, FTP layer issue, Media Upload issue
SecFilterEngine Off
SecFilterScanPOST Off
########## End - Attempt to solve 'Global Configuration' save issue, FTP layer issue, Media Upload issue

I got this code from this url:
http://forum.joomla.org/viewtopic.php?f=431&t=265427&p=1216787

After updating my .HTACCESS file with the above code , My problem resolved.

Just for information:

swfupload failed when trying to use it in maintenance mode. '503 Service unavailable'
Switching back to online solved it. Just so you know.

A lot of server issues/questions can be answered here: http://swfupload.org/forum/generaldiscussion.

#10 is included in README.txt. Thanks for reporting!

I had the same problem. However, after I added the lines per #10, I could not even connect to my site. When I tried to connect, I got the following error:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

I think the lines in #10 turn off mod_security, and if your hosting company doesnt allow you to do this via .htaccess you'll get a internal server error I think. You might have to ask them to disable it for you.

I had the same problem. When i'am upload files swfupload print "server error". The site was offline. Once I did it online problem has been fixed.

p.s. sorry for my english
