    • > /wp-content/plugins/cp-appointment-calendar/dex_scheduler.inc.php
  • 3× PHP files trigger errors when accessed directly with GET requests:

      Uncaught Error: Call to undefined function get_site_url() in wp-content/plugins/cp-appointment-calendar/dex_appointments.php:29
    • > PHP Fatal error

These attributes need your attention:
  • Screenshots: These screenshots do not have images: #1 (Inserting the calendar into a page.), #2 (Booking/reservation form.), #3 (Calendar configuration and administration.)
You can look at the official readme.txt

cp-appointment-calendar/dex_appointments.php 92% from 13 tests

"CP Appointment Calendar" version 1.1.38's main PHP file describes plugin functionality and also serves as the entry point to any WordPress functionality
The following require your attention:
  • Main file name: The principal plugin file should be the same as the plugin slug ("cp-appointment-calendar.php" instead of "dex_appointments.php")
