vBulletin Integration - just so you know...
 

I have had problems in the past with users using punctuation in their user names, such as O'Henry not being able to log in on the classifieds. I am using the vBulletin user base for registration, user names and passwords. My classifieds installation is on a different domain name, but it is on the same server and it works absolutely great!

In the vBulletin admin panel, User Registration Options, Username Regular Expression, I placed ^[A-Za-z0-9. -]+$ to prevent folks from registering with anything but numbers, letters, spaces, dots or dashes in their user names.

However, this does not prevent them from placing weirdness in their passwords. I just had a user with &, #, ! and % in his password. Wonderful for security and it works for logging into vBulletin...

BUT, this will not work for a user logging in on my configuration of PhotoPost classifieds, using the vBulletin user base on a different domain. As I said, this is posted just so you know. :cool:

You can send to support@photopost.com full server info logins urls and descriptions users passwords etc database viewers and we can see if we can determine what your issue might be.
