Forum page not found
 

Suddenly, with no changes applied, my forum and admin login page started returning 404 - page not found. Actually, every forum related page returns 404. The site itself works fine. I'm running the latest suite version 4. Before I start with overwriting all files via FTP, I wonder what do you think where I should start from.

Thanks

To add: I just renamed .htaccess and got the forum back. How do I regenerate it? I do use VBSEO. Thanks
