class_core.php error

[Virtualshiner]

Hi,

When trying to view a new thread, I get this error:

Unable to add cookies, header already sent.
File: /home/vfkforum/public_html/forums/includes/class_core.php
Line: 3254

I have tried uploading this again file again but the error is still there. I have also contacted the vBulletin ticket support system and they said that we found out its a plugin error. Can anyone help?

I have deleted the files for the newest plugin we installed yet that didn't work either.

Any help?

Thanks,

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

define('DISABLE_HOOKS', true);

If that fixes it, then you still have the bad code on your site. Maybe it was a plugin you installed before the last one. You'll have to disable them one-by-one to find the problem.

I did that and the problem goes away.
I am like 90% sure its that flashchat integration mod we added yesterday causing this. I have deleted all that but still experience a problem.
