How To Fix The HTTP Error & “Specific File Not Found.” Errors In WordPress 2.5

Posted Apr 3, 2008

On March 18, I read and wrote about the new features of WordPress 2.5. When Automattic released 2.5 days later, I upgraded right away. But to my disappointment, there were some bugs when using the open source blogging tool on Windows Vista: on both IE7 (Internet Explorer 7.0) and Firefox 2.0. These errors were directly associated with the image upload and media library tools. I’ve managed to resolve the issue by reading WordPress forums.

Here is how you fix these errors.

Go into the root folder where you copy the wp-admin, wp-includes, wp-content folders. In that folder is a file called “.htaccess.” You need to edit this file so that the below code is inserted before # END WordPress.

The code that needs to be inserted before END WordPress is:
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off

After inserting that code, WordPress 2.5 should work in Firefox.

Internet Explorer 7.0
Make sure that you edit the same code above for Firefox. The .htaccess file needs to be edited along with the other following files.

In the file, ” root folder /wp-admin/includes/media.php “, there is a comma that throws off the photo upload tool. Here is the code that throws it off.

file_queue_error_handler : fileQueueError,
file_dialog_complete_handler : fileDialogComplete,

debug: false,

See that comma after debug: false? Delete it.

One more file has to be manipulated for WordPress 2.5 to work in IE.

In the file, root folder /wp-includes/js/swfupload/handlers.js
There is a line of code that says:

.animate({minHeight:0,height:36,}, 400, null, function(){jQuery(this).children(‘.describe’).remove()})

See that comma after height:36? Delete that comma! Make sure to save both files after deleting the commas and then WordPress 2.5 should be fully functional in both IE and Firefox. I literally figured this out 5 minutes ago. Let me know if it works for you.
