For some reason the Latest Events module has stopped working. I'm able to display the latest events (as usual) but now when you click on an event, you get an error message:
Forbidden
You don't have permission to access /http://index.php/promotions-calendar-2/icalrepeat.detail/2018/01/25/29277/92|93|89|96|97|101|102|104|105|107|111|112|146|147|149/700-000-mercedes-match-guaranteed-giveaway on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
There's no problem accessing the events from any of the calendars, only from this module.
What could be causing this?
