More problems....
 

Users are saying when they register and then click to go into a forum they get this message

"our records show that you have already registered under the name of NAMEHERE If you have lost your password, click here. If you would like to modify your profile, click here."

Please let me know a fix asap.

Thanks.

Link? And I assume the user isn't already registered?

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

This has happened when we enable vBSEO and FB connect at the same time.

I just was able to register with no problems (can you delete the account Lynne on your site) and then click the link to the Forums and I got no message at all, just the forums page.

edit: Oh, I see, then they click to go into a forum and get that message. I am fine clicking any page that isn't vbseod, so I would say that you have some vbseo settings set incorrectly.

Any idea what the setting would be? I think it may be a redirect error as or forums path is /forum but it redirects to the root. Any suggestions?

I do not know vbseo, so I don't know what that setting would be.
