    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_action() in wp-content/plugins/debug-bar-post-meta/debug-bar-post-meta.php:21
    • > PHP Fatal error
      Uncaught Error: Class 'Debug_Bar_Panel' not found in wp-content/plugins/debug-bar-post-meta/class-debug-bar-post-meta.php:15

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)
No browser issues were found


Plugin configuration 97% from 29 tests

readme.txt 94% from 16 tests

These attributes need to be fixed:
  • Screenshots: Please add an image for screenshot #1 (Sample of post meta.)
