SRP 0% from 2 tests

    • > /wp-content/plugins/external-login/views/modal.php

    • > /wp-content/plugins/external-login/views/form_elements/button.php
    • > /wp-content/plugins/external-login/views/partials/wpconfig_option_set_message.php
  • 47× PHP files trigger errors when accessed directly with GET requests (only 10 are shown):
