I'm using Toolset and custom user registration and login screens. I've found when I have User Verification enabled I am unable to login as my admin or editor users. I can login with the subscriber user created under User Verification. Please advise.
Welcome to our forum.
There is an option to disable user verification by user role, you should use the option "Exclude these user roles to verification?"
your custom login form should be implemented with login errors to display error from user verification plugin, otherwise please ask to the 3rd party plugin author to implement it.

if you can see the login error you will see there is verification resend link which will allow any user to resend verification mail. and this way admin can get verified.
Hope you understand.
