Is there anyway to fix this error and how?

Disable it?

I uninstalled this mod right after i got the error on user emails.I'm wondering about re'adding back the default column .If i could get the default column from you guys and explain for me where to add it.

If the error does not occur, you don't need to do anything...

It does because all new members when they register they get confused and never confim their email address because of this error.
What a bad luck :(

To troubleshoot this, please remove any hacks and disable your plugins, then 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 so, 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.

rgr that will do. Thank you sir <3
