404 errors after new posts

When i have my .htaccess file enabled when you try to view threads or post replys i get 404 errors. any one have any ideas? i am using the default .htaccess file. this happended after i moved my site to a new server.

Hello,

please make sure that your new host supports mod_rewrite.

it does and it is referenced in my apache config. when i turn vbseo on the forum index loads fine and i can etner each forum but it some times gives 404 errors when trying to view threads and always gives 404's after you post a reply and the url changes to showthread.php?

Please provide testing account via support ticket and include example URLs. Thanks.
