Thread:Project:Support desk/403 error, CSS mess, only on IE/FF, not on Chrome/reply

I've tested with Google Chrome with exactly the same problem.

It seems that every page with a "=" character in the URL leads to a 403 error. Check the apache error logs to see if there's more info about what's causing the forbidden errors. If you have rewrite rules enabled, please remove them to see if they're causing the problem.
