Forum Uploading Images on posting a Thread
 

Our forum members are unable to "Add an Image from your computer" when posting a new thread. They can add an image from a URL without any problems.

I have checked the attachment size & permissions (1MB), changed the storage type to directory with chmod 777, checked the image settings (on GD) and tried using safe mode and adding information to the vhost.conf - all without any success.

The image uploads and then a red exclamation mark appears, which when you hover over it says "undefined".

Any help would be appreciated.
