Post and edit functions not working properly

I'm pretty new to this whole vB thing, I'm more used to IPB, but I've recently decided to broaden my horizons.

Anyways, I'm currently running vBulletin 3.6.8 Patch Level 2 and MySQL 4.1 and I'm having some problems with the post and edit functions. When I try to post a rapidshare download link i get an error.

For example, if I try to post the following link:


http://rapidshare.com/files/70863989/Under_A_Cyber_Moon_CS.rar


I get the following error:


Not Acceptable

An appropriate representation of the requested resource /newthread.php could not be found on this server.


And if I try to edit a link like that into a post I get the same error where "newthread.php" is replaced with "editpost.php"

I've looked through both of those scripts and as far as I can tell (woth my limited knowledge of PHP) there's nothing wrong with them (although that's not to say that there isn't anything wrong with them).

If anyone has any possible solutions to this problem I'd be glad to hear it.

might be a errored file uploaded. reupload everything except config.php and see what happens....

thanks for the reply... i'll have a try of uploading everything again but i'm not sure if it'll work because i haven't changed any of the settings in the post/edit scripts... but i'll give it a try and get back to you

EDIT: Nope its not any of the files... i've totally reloaded the server, even reverted to an older version of vB (3.6.7) and had no luck... i guess i'll have to keep trying
