Firefox users unable to upload

[starman]

I am running 2 vbullentin sites version 5.01. In both galleries members are unable to upload images.

Firefox
When they click the submit button they receive an error "No data in the document". In IE there are no problems.

IE
When they click the submit button they receive a page not found. However if you click the back button and submit again it does go to "Preparing to process images page" It appears to try to process the images but then it takes it goes to a page with message. "No more images found.
Click here to return to gallery."
