NamelessMC

Ok, I have this error, how to solve it? 

 

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'incoming_email' for key 'nl2_settings.name'

 

It happends when I try to install NamelessMC at "Site Configuration"

 

This is the error when an user tries to register or to login.

 

There was an error loading this menu. The website owner needs to follow these steps to fix it:
1. Make sure the hostname value in core/config.php in FTP matches your site url.
2. If you are using the www. prefix make sure the force www option is enabled in StaffCP -> Configuration -> General Settings.

This is the error when an user tries to register or to login.

It Works but when I try to register on my site this appear. I followed the instructions in the error but it doesn't work.
