 * Hello guys, I’m running the lasted version of flash and wordpress 3.1.3 and all
   of a sudden the flash uploader stoped working.. I did a search here and everything
   seems to be dated back to 2008 and non of the solutions work.
 * What is weird is that I have 3 wordpress sites, it’s not working in only one 
   of them, the other two works fine. The only thing I did to this installation 
   is messed with my theme functions.php file;
 * I added;
 *     ```
       if ( function_exists( 'add_theme_support' ) ) {
       	add_theme_support( 'post-thumbnails' );
       	set_post_thumbnail_size( 150, 150, true ); // default Post Thumbnail dimensions (cropped)
       	add_image_size( '55x55', 55, 55, true ); // Widgets
       	add_image_size( '512x240', 512, 240, true ); // Blog Index
       	add_image_size( '512', 512, 99999, false ); // Single
       }
       ```
   
 * as soon as I saved that it stopped working, I tried reverting it, but the problem
   is still there.
 * Any ideas?

 * We’re getting the same thing with our sites — the file is still uploaded however.

 * Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the Twenty Ten theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.

 * That what was my problem, a plugin was causing it. So if anyone is having trouble
   with this, do as ESMI mention above before going crazy and trying to fix it by
   all the methods described when you search for this problem.

 * It’s not a plugin for us (other than a select few, that aren’t currently installed,
   we don’t use them) but does seem to be theme-related as it works without a hitch
   with the Twenty Ten theme.
 * I’ll try gutting the functions file to see if it’s in there. Thanks for the help!

 * Turns out it was being caused by a redirection script I had running in the Admin
   area. Easily fixed.

 * My sites have been running for quite awhile when suddenly I can’t upload any 
   image and getting the HTTP error message. So it couldn’t be any work on the theme.
 * It can’t be the plugin either as I have just upload a new website with new WP
   installation and none plugin activated yet. Yet I still could not upload any 
   image.
 * And it couldn’t be the theme because even with Twenty Ten 1.2 I still get the
   same error message.
 * Please help.

 * Ruzie,
 * I would contact your hosting provider and see if they changed/updated anything
   that may be causing this.

 * Thank you, gldtn.
 * I’m checking with them now. It seems they’re in the midst of increasing the Max
   File Size limit in MySQL. Maybe that is the cause of the problem. It’s quite 
   frustrating though coz meantime I can’t get any work done… 🙁

 * In my case the uploader works when in the media library, but not when writing
   a post. I’m actually not getting the usual http error, it seems the select files-
   button doesnt do anything.
