Everything seems fine, however this is by no means an exhaustive test

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
  • 2× PHP files trigger errors when accessed directly with GET requests:
    • > PHP Fatal error
      Uncaught Error: Class 'GFForms' not found in wp-content/plugins/gf-facebook-pixel-tracking/includes/GFFBPT_Submission_Feeds.php:12
    • > PHP Fatal error
      Uncaught Error: Class 'GFForms' not found in wp-content/plugins/gf-facebook-pixel-tracking/includes/GFFBPT_FBP.php:2

User-side errors Passed 1 test

🔹 Test weight: 20 | Just a short smoke test targeting errors on the browser (console and network errors and warnings)
Everything seems fine on the user side
