Thank you for geting back to me.
Any changes that are made in the Joomla backend are then also changed on the frontend as expected. It's only when a user tries to change a repeating event on the front end that it the repeat events aren't updated.
So, if I change the event details in the front end, i.e. the repeat frequency, amount, days etc, none of the repeated events are affected, even though the details are stored in the main event. In the backend when I change an event an alert message pops up explaining that all repeat events will be deleted and new ones created, but I don't get this message in the front end, if that means anything.
Thanks
Bobby
