Thx for the help, but...

Let me explain my problem.
Yesterday i installed a clean PHPnuke 6.5 and I installed the Site Visitor block. Afterwards i noticed that i couldn't log in using the login from the site visitor block, but i could with the normal login block. So i decided to remove the login function from the site visitor block.

To my surprise, after removing the login from the site visitor block, i couldn't login anymore using the normal login block.

After undoing the changes to the visitor block it worked again, except the login from the visitor block.

Any suggestions ???
