I was under the impression that the login page was built using Toolset but you are using the Login Customizer plugin to create the login page.
I'm not sure how we will be able to resolve this one but the issue is definitely interfering with the login customizer plugin's ability to log in non-admins.
Could you contact their support team to see if they are able to resolve this one for you. I'm not seeing how wordfence conflicts with toolset.
Shane, if there is a tutorial on how to customize the wordpress login page using Toolset, I'm all ears.
I thought Customizer plugin would just do that, customize the login, not interfere with the login. And every time I turn off Wordfence, I'm able to login just fine. I might have to contact Wordfence instead.
I believe there was a plugin conflict. I deactivated Limit Login Attempts Reloaded plugin and Google Captcha (reCAPTCHA) by BestWebSoft plugin and reactivated Wordfence.
It seems now that Users can login. At least the ones I tried. Could you try to login in your end since it has a different IP and see if it works?
