Hello!
When activating notification function of the events ("Notification: [ ] now and/or [ ] day(s) before event"), LuxCal sends the message right away, but do not sends any notification related to [X] day(s) before event.
For example, if I create an event and configures it as "Notification: [ CHECK ] now and/or [ 1 ] day(s) before event", LuxCall will send an email to the recipients; but, the day before the event, it won't send any.
By the way, at the beginning I had problems with activating notification feature. Was having some trouble because of WordPress configuration, so I had to install and configure PHPMailer for SMTP.
I have not much knowledge about code and web or software development, however I can learn...
