Error, don't know what it is.

So I am getting this error and it prevents anyone from being able to go to my forums.
Here is the message it displays:
[CODE

Warning: preg_match() [function.preg-match]: Unknown modifier '/' in [path]/includes/init.php(298) : eval()'d code on line 7

Unable to add cookies, header already sent.
File: /home/*/public_html/*/forums/includes/class_core.php
Line: 3277

[/CODE]

Does anyone know what this could be?
Should I just upload new class_core.php and init.php files?

Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

PHP Code:

define('DISABLE_HOOKS', true);

Thanks! It worked. I guess the plugin was messing it up. I disabled the plugin now and then changed back the config file.

Thanks a lot!
