منتدى استراحات زايد - Forum Error when loading forum homepage

Hello,

Our forums have been working for awhile now; however this morning I tempted to add an activity product. As soon as I added it the forums homepage died when I tried to load it. I immediately removed the product, but the damage was already done.

Silly me thinking this was a minor add-on I didn't do a backup. :(

Here is a breakdown.

1) The product file attached is what I originally had used.
2) The website loads all other tabs (activity etc) and I can even access threads if I know their link, but the actual forum.php (our forum homepage) won't load.
Link: http://www.subeta-unique.com/forums/forum.php
I get the error "Server error

The website encountered an error while retrieving http://www.subeta-unique.com/forums/forum.php. It may be down for maintenance or configured incorrectly.
Here are some suggestions:

Reload this webpage later.

HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request."

3) I disabled all current plugins with the config file and that did not fix anything so I reenabled them.
4) I am not getting any errors sent to my email and I created an error file (not sure if I did it 100% correct...) but nothing was being added to the log there either.

I even replaced my forum.php with a fresh one from vbulletin but nothing changed. Not sure what to do!
