When trying to log in after enabling 2FA on my account, at first it was saying "Error" when I tried using the regular sign-in form while entering my password.

Disabling the plugin allowed me to log in, then enabling it again brought up the Verify screen. After putting in my code from the authentication, it simply produces a blank white screen with no errors. Refreshing any page will need to enter a code again, but it doesn't go through and white-pages each time.

This is the error in my log,

[Notice] Message: Undefined index: lang File: /var/www/example.com/public_html/ow_smarty/template_c/9cbe14dd24d3a006ac7daa2037e7436a0f74d877_0.file.login_setup.html.php Line:128

The plugin seemed to work when I put the site into Dev mode, so I'll have to look into it some more tomorrow. Any guidance would be appreciated though!
