Thanks for the prompt reply.
There is no related errors in the error.log file unfortunately.
There is not much to configure with WP Mail SMTP plugin as long as I choose “Use the PHP mail() function to send emails” so I don’t think they can help me either.
Just to clarify, Booking Calendar uses the PHP mail() function, correct?
What are the known plugins that could interfere with Booking Calendar notification function?
Thanks for getting back to me.
I have installed WP Mail SMTP plugin and set the Mailer option to “Use the PHP mail() function to send emails” but still Booking Calendar does not send notifications.
I do not think other plugins are interfering with Booking Calendar because it was sending notifications before we upgraded it to 7.1.2.12.
Any other ideas to troubleshoot this?
