XF 1.5 Users can't register. Errors showing up.


Active member
Hello I have an issue where users can't register a new account. Below code is when I try to create a user in the back end. From the front end the user just gets and error from the moment they input a user name. Registration page: https://www.forum.motorcyclenews.bike/register/

Any suggestions of how to fix would be grealy appreciated. Thanks?

Xenforo 1.5.15
