 * Hi, hope you can help me as soon as possible as she wants to add discounts for
   Black Friday this week. I have updated my client’s website to the latest WordPress
   version but now the plugin doesn’t work anymore. At the last step of the booking
   form, at checkout, the page loads but then shows just an “0” => [https://www.johanah.com/wp-admin/admin-ajax.php?lang=en&sln_step_page=services](https://www.johanah.com/wp-admin/admin-ajax.php?lang=en&sln_step_page=services)
 * This is the following message:
    Notice: Undefined variable: page in /customers/
   4/1/7/johanah.com/httpd.www/wp-content/plugins/salon-booking-system/src/SLB_Discount/
   Plugin.php on line 189 Notice: Undefined variable: post in /customers/4/1/7/johanah.
   com/httpd.www/wp-content/plugins/salon-booking-system/src/SLB_Discount/Plugin.
   php on line 190
 * Looking forward to your help.

 * Thank you for your reply. If that is not then how come the checkout doesn’t work
   anymore? How can I fix this?

 * Hi,
 * the file you have linked is not related to salon booking system.
 * Anyway enable the wordpress debug_log and then make a test again, then open the
   debug.log file and report the php error. Make sure you look for PHP ERROR, not
   warning or notices.
