      Uncaught Error: Call to undefined function esc_attr() in wp-content/plugins/convertkit-gravity-forms/vendor/convertkit/convertkit-wordpress-libraries/src/views/review-request.php:11

    • > PHP Fatal error
      Uncaught Error: Class 'GFForms' not found in wp-content/plugins/convertkit-gravity-forms/includes/class-gfconvertkit.php:9

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