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

  • 1× GET requests to PHP files have triggered server-side errors or warnings:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function get_option() in wp-content/plugins/flippingbook/flippingbook.php:47

User-side errors Passed 1 test

🔹 Test weight: 20 | A shallow check that no browser errors were triggered
There were no browser issues found
