Edit Post button not working

Seen this issue a bunch around the forum (1, 2, 3, 4, 5) with no solid solution.

I’m having an issue with the Edit Post page where most of the links do not do anything when I click on them. Screen options dropdown, “Text” toggle for the editor, “Edit” for the Permalink, etc. I look in my console and here’s the error I receive:

Uncaught Error: cannot call methods on sortable prior to initialization; attempted to call method ‘toArray’
Uncaught TypeError: Cannot read property ‘hasClass’ of undefined (wp-auth-check.min.js?ver=4.6.1:1 )

Adding define(‘CONCATENATE_SCRIPTS’, false); to my wp-config.php file did not resolve the issue,

I did deactivate my Restrict Content Pro plugin and it resolved the issue, but that’s my membership software plugin, so I need an alternative solution.
