Disabling Hooks

[Easelm]

I have recently moved my website to a new server location
and everything works fine. Except for the forums, I get a 500
Internal Server Error. When I set the php string to disable
hooks in the config.php, the forums work.

Although, I have tried to disable the plugins through the AdminCP
then commented out the hook disable string in config.php, but I
still end up with a 500 error. Also tried removing all the hooks
entirely and even tried re-uploading and installing them, but the
forums will only work when I have hooks disabled in the config.

Any suggestions?

Side note: I run the server the site is hosted on, and all user & group permissions
on the files are correct. Also has chmod 644 on the php files and 755 on the folders.
