WordPress 2.5 Image Upload Solution

The newly released WordPress 2.5 has media uploading issues. The suggested solution is to add a few lines of code in the .htaccess file.

One more important thing especially for Linux users is to upgrade to the latest version of Flash which is available for download from Adobe. The latest version I installed on Ubuntu was 9.0 r124.

This can be checked out by opening a new tab in Firefox and typing about:plugins. Check under Shockwave Flash and the version number should be there.

This is not only applicable for custom WP installation but also for blogs hosted at wordpress.com.

BTW, the lines of code that should go into the .htaccess files are this.

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off

If you do not have a .htaccess file, create one and place it at the root of your website. If you already have one, add this code at the end of the file.

Happy Uploading 🙂

  1. I have added this code and I have the current Flash player plug in.
    I still get a Fatal Error message:
    Fatal error: Call to undefined function wp_constrain_dimensions() in /home2/newyorka/public_html/wp-admin/includes/image.php on line 173
    I am getting desperate,


  2. @sage, I am not sure what the problem is. But a little googling helped. If possible try to re-install WP. Else please have a look at the following URL.
