The users_LogOut was created by Security Assist as a separate page and I am told that it clears all of the session variables. Somehow it has been fixed in this problem when the computer was restarted, but a client should not have to do this. When creating the cart with WebAssist e-cart, and checkout goes to checkout.php. In this case the checkout button went to logout instead form an unknown reason. As Jason did look at the code and found no problem on the LogOut pages and I have not found any other re-direct issues.
Just FYI to Lon Winters.
