I am getting an error page after registering.
42 - Failed to update contact: COM_CONTACT_ERROR_UNIQUE_ALIAS

But if you click the back button and enter the password again it works ok!
Also I have to approve in the back end.
Also when I click on the user name to go to the profile it is sending me to the Home page and at the bottom of the page is the profile.
with an error message
Warning: overlandarena.com/index.php/component/comprofiler/?user=529&Itemid=101 is unreachable.

Please help me fix this. I have a site launch this week.
Thanks
Leigh
