On /scp/profile.php trying to "Configure options" on "Default 2FA" show error:
profile.php:175 Uncaught TypeError: $.dialog is not a function at HTMLButtonElement.onclick (profile.php:175:15)
Same error when adding the plugin for mobile application

Look for any logs on the server. It’s also possible your server has security rules that’s blocking JS, etc.
