Even though no errors were found, this is by no means an exhaustive test

SRP 0% 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
Please take a closer look at the following
  • 2× PHP files output non-empty strings when accessed directly via GET requests:
    • > /wp-content/plugins/woo-mailerlite/includes/views/components/woo-mailerlite-modals.php
    • > /wp-content/plugins/woo-mailerlite/includes/views/components/wizard-breadcrumb-component.php
  • 21× GET requests to PHP files trigger server-side errors or Error 500 responses (only 10 are shown):
