Hi sbillard, thanks for your help.
I think I figured out why I got access completely blocked. It was because I had the [i]failed_access_blocker[/i] plugin active, whoops.
Is that what happens with that plugin?
Anyway, I installed a complete fresh copy of ZP, load the Zenpage theme, goto plugin tab and activate the [i]user_login-out[/i] plugin and than set the [i]Enable login form[/i] to ON (OFF doesn't doesn't display anything anyway).
Now when I go to index.php I see the logout link.
When I log out I get a form with ONLY the password field.
Trying to use my password fails.
Actually that is why after trying +10 times the [i]failed_access_blocker[/i] blocked access and after one hour I could get in again, right?
So what happened with the username field?
