Specific user role can't log in
Thanks for the help.

I did try to login with an email and username, same results for both.

But very strangely everything works now...
And i have no idea what i did to fix it.

Last thing i did was update every module and the Drupal Core.
And today the login form works again as it should...

I would love to give more information for future people experiencing this problem but frankly i have no clue what solved it.

Thanks again for all the help!

Greetings
