I have the same issue as well, I am getting "You can't access the private section of this site." and " You are not authorised to Manage Events" My client is a Chamber of Commerce for our Parish and they have it setup to post events on the website in the top right corner but I have been unable to get past this part for a month or so and they are on my butt about getting the calendar back up so that the community can see the upcoming events. I have turned off the autherised user feature, I have made her user the admin for the calendar and every other hint I could find but still can't even get her logged in to get past that to look at the reason that it is not posting to the web. This seemed to have happened when I changed hosting companies. The old host was a linux centos 6.7 and no panels and was fully managed. This one I have cpanel and CLI and cannot get it to work. Somone please give me a hand with this. stmarychamber.com. If I login there with my superuser login, it goes to "https://stmarychamber.com/calendar.html" with 403 error.
