SRP 50% from 2 tests

🔹 Tests weight: 20 | A shallow check of the single-responsibility principle; PHP files should perform no action - including output of placeholder text - and trigger no errors when accessed directly
The following issues need your attention
  • 3× PHP files trigger errors when accessed directly with GET requests:
    • > PHP Fatal error
      Uncaught Error: Class 'Mtm_2F_Methode' not found in wp-content/plugins/2-factor/includes/Mtm_2F_EMail.php:4
    • > PHP Fatal error
      Uncaught Error: Class 'Mtm_2F_Methode' not found in wp-content/plugins/2-factor/includes/Mtm_2F_SMS.php:4
    • > PHP Fatal error
      Uncaught Error: Call to undefined function __() in wp-content/plugins/2-factor/mtm-2f.php:13

User-side errors Passed 1 test

🔹 Test weight: 20 | This is a shallow check for browser errors
Everything seems fine, but this is not an exhaustive test
