I had the same problem. I have over fifty WordPress installations. Some of my sites had problems after the auto upgrade. None of the sites that I manually upgraded had issues. After doing all the usual tricks a complete manual re-intall was the only solution that worked. I use Host Gator. I followed the steps here http://bit.ly/RbU5qG. with the following exceptions:

I created a new “Old Files” folder.
I moved all the files except the WP-Content folder to the new old files folder.
I downloaded the latest WorddPress 3.5 to my local PC.
Extracted the files and deleted the WP-Content folder then re-compressed.
Uploaded to the server and extracted them.
Copied the WP-Config.PHP back to the root.

Make sure to disable all Plugin-ins. Then re-enable after manual install.
After that everything was good as new.
Hope that helps.

Have you gone to “FIAGallery” > “Options” > “Roles” and set the lowest level for each role?
