Moduals Displaying Page Not Found

All My modals are displaying a 404 error page. I dont remember changing anything. It just suddenly happened. Is there anything I could try to fix it. I've tried disabling permalinks, that doesnt work. Please help! Thanks!

Site: my-cabinet.com

Furthermore, the Videos modual wasn't allowing anyone to embed videos from YouTube. Could this have been caused by something my host changed? But now I cant even test that since none of the moduals are working.

Thank You So Much For Your Help! Let me know if there is any more information I can give.

Does anyone know what to try? My facebook connect app wont even work now! :(

If permalinks were working previously, something may have changed about the server setup.  if this is a shared server, ask your hosting provider if any recent changes were made to Apache and if mod_rewrite is no longer enabled.  You should also try using a new .htaccess file from a download in case the current one was edited.

Edit: Moved.

Ok. This is what i found wrong when i checked codman212's server. Incase Other run into problems. These are other things to check.

I do not know how or why these things happened all of the sudden, but they did and i am kinda wondering if his host moved his site to a different server.

Permissions on the following folders were not properly set.

cache
cache_public
tmp
lang

PHP settings were off. allow_url_fopen was off and it must be on.

index.php was missing from the modules folder.
