Quite a few weird errors that has me stumped.

1st error which runs down the top left of the board

Warning: Division by zero in /global.php(334) : eval()'d code on line 182

2nd error after I enter my password on the AdminCP

Unable to add cookies, header already sent.
File: /home/kgdseip/public_html/vbulletin/includes/class_core.php
Line: 2984

Lastly 3rd error just clicking on a topic or forum

Warning: Cannot modify header information - headers already sent by (output started at /home/kgdseip/public_html/vbulletin/includes/class_core.php:2984) in /includes/functions.php on line 2394

I am pretty new to the coding part of VBulletin but am savvy enough to fix issues if I know what they are, any help would be appreciated.

They are most likely caused by modifications. DIsable all of your modifications and see if those messages disappear.

thanks, how do I go about disabling these? Do I simply remove the modification files? I cannot get in the AdminCP at all so I hope I don't have to do it from there. Thanks in advance.

Add this to the end of your config.php file (before ?>).
define('DISABLE_HOOKS', true);
