Profile Problems - User's Registered, but profile seems to be gone?
 

I noted this a few weeks back and haven't been able to dig into until now, and I am befuddled.

A large number (actual number unknown) of our members seem to have profile issues, as if they do not exist, or have not registered, but they have.

When I, or any member, click on one of these profiles, the following is displayed:

Code:
This user has not registered and therefore does not have a profile to view.
For example:

http://www.nbssportfishing.com/vBforum/members/gp-tj/

The above is just one of many, but all the same.

The above example member joined on 01-04-2007

It doesn't appear date related, as others before and after look OK, but I have noted well over 20 of these just randomly clicking on profiles over the past few weeks.

Has anyone ever seen this or know what may be causing it?
