I can't delete my previous question.
(https://easy-appointments.com/support/mail-error-you-must-provide-at-least-one-recipient-email-address/) IT SEEMS THAT THE ERROR IS NOT CONNECTED WITH THE EMAIL BECAUSE I CLEANED THE LOG RECENTLY AND THE ERROR CONTINUED TO HAPPEN, BUT THE LOG STILL CLEAR. THE TRUTH IS THAT I DON'T KNOW WHAT COULD BE CAUSING THE PROBLEM BECAUSE I DON'T HAVE ANY MORE DATA. WHEN I COMPLETE THE FORM DATA FOR THE RESERVATION AND SELECT CONFIRM, A POP UP IS SHOWN SAYING THAT SOMETHING WENT WRONG. THANKS
