Request Internal Server Error when trying to Sign-Up

[Kiad]

Hello!
First of all I would like to thank you for this page trying to help me.
So here's my problem: As soon as I try to register on my forum, or dice that someone other than me trying too, an error message occurs:
"Internal Server Error"
Could you help me please?
Here is a screen of the error itself.

That was an little error.
The solution is: Go on the Admin CP -> Options -> Account options then disable verification.
