Registration not possible

[alcaporzel]

Hey friends,

we just installed Coppermine on our Server.
Unfortunately is not possible, that users can make registration.  The Link appears and we can set our user data, but after clicking for registration nothing happens. Just a black windows or a naked window.
As you all can try -> https://motteritos.de/coper/register.php

Nothing happens. What could be the error. Installation and all went well

Thanks a lot
Greetings

Did you install any plugins? An improper plugin may cause this to happen.
Set debug mode to show debug messages for everyone (with notices) to see if it reveals a clue.
