I tried to post an event to the SL Events Calendar this morning. The calendar seems to be stuck on 9/23/19. When I press the forward arrow, the grayed out page number at the bottom of the page changes, but the actual page does not change. I wanted to post an event for Tuesday, 9/24/19, but can't seem to get the calendar to change days from 9/23/19. HELP PLEASE!
