Thank you for pointing that out.

in my app/Http/Middleware/CustomPasswordBroker.php


Changed: 
use Illuminate\Contracts\Auth\UserProvider;

To:
use  App\Http\Controllers\Auth\CustomUserProvider as UserProvider;

Seems to fix the previous issue but now I get

Unresolvable dependency resolving [Parameter #3 [ <required> $emailView ]] in class App\Http\Middleware\CustomPasswordBroker

You have interface( ), and this classe is implementacion, you have $emailview that is a content of view? Is that?

Sorry I'm not sure what's going on here. This was copied from an example online but it only seems to throw an error when I try and use the password reset link.

Yes I am too. I'm sorry I haven't had much time to work through this. Will get back to you definitely if I figure out why this is happening.

Thank you for your help so far though.
