Joomla version 3.9.18 JEvents version 3.6.13 (updated to 3.6.15 but rolled back as I thought it was an update error)
When updating one of my calendars I get a 500 Internal Server Error, but I am able to update all of the other calendars. Creating a new calendar seems to have the same problem. I have tried searching the forums but cannot find a similar issue. The console log says: crbug/1173575, non-JS module files deprecated but I am unable to find a solution based on that error as well. I have cleared my browser cache, Joomla cache, and my DNS Cache all to no avail. Please help.
