Hello kb12321,

Could you please tell me have you followed these steps? 

In the Tools -> Cron Events admin panel, 

click on the “Add PHP Cron Event” tab underneath the cron event table. 

In the form that appears, enter the schedule and next run time in the boxes. The event schedule is how often your event will be executed. In the “PHP code” area, enter the PHP code that should be run when your cron event is executed. Please insert this:

file_get_contents("https://yourwebsite.com/wp-admin/admin-ajax.php?action=wpamelia_api&call=/notifications/scheduled/send");

You don’t need to provide the PHP opening tag (<?php).

Please replace "https://yourwebsite.com" with your real web address.

If you don’t see a good interval, then add one in the Settings -> Cron Schedules admin panel or click on link "Manage Cron Schedules". You will find example how you can make custom interval inserting:

• Interval name
• Interval(in seconds)
• Display name

and click "Add Cron Schedules" and it will be added.

When you made custom interval you need to go back to  Tools -> Cron Events admin panel and click on the “Add PHP Cron Event” tab underneath the cron event table where you will insert that custom interval and all other field that are described above. After clicking on "Add PHP Cron Event" it will be added on Event table and you are done.

Is the cron created like in the above picture? Where exactly do you get the error message, could you please send me a screenshot? 

Thanks!

Hello kb12321, 

Could you please try setting cron up in the "Add PHP Cron Event" not in the 'Modify Cron Event'? 

And set the 'Next run' on "Now". 

Thanks!

Please let me know if you still have issues, 

Hello kb12321,

Could you please tell me have you tested these notifications? (Making some fake appointment) And didn't get the notification? 

Thanks!
