What Causes This Registration Error

[MarketProfits]

my forum currently has this error upon registration:

[B]Warning[/B]: strpos() [[URL="http://www.vbulletin.com/forum/function.strpos"]function.strpos[/URL]]: Empty delimiter in  [B]/includes/class_dm_user.php(2484) : eval()'d code[/B] on line  [B]11[/B]

What is causing this error which appears on top of the header?

Also, the vbulletin message associated with this error is :

Unable to add cookies, header already sent.
File:  /home/username/public_html/includes/class_core.php
Line: 3075

Help me someone.

That appears to be from a modification.

To troubleshoot this, first reupload all the original vB non-image files (except install.php). Make sure you upload these in ASCII format and overwrite the ones on the server. Also be sure to upload the admincp files to whichever directory you have set in your config.php file. Then run 'Suspect File Versions' in Diagnostics to make sure you have all the original files for your version and that none show 'File does not contain expected contents':

Admin CP -> Maintenance -> Diagnostics -> Suspect File Versions

[Note: In some cases you may also need to remove any of the listed .xml files in the includes/xml directory.]

Next, disable all plugins.

Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

Then if you still have this problem, create a new style and choose no parent style. This will force it to use the default templates. Finally empty your browser cache, close all browser windows then try again. Make sure you change to the new style and view your forums with it.

Do you have the same problem?
