I have the same issue of an empty month view, and when I try to do the hot fix (update my Events Calendar PRO), I see a message that I’m “out of installs.” I followed the links provided by Modern Tribe in the help section to find my license key history and what domains they might be on, but there is no information there. I have the latest WP version. The URL that automatically pops up is DesignForSite.com, which is our web designer, not the website he designed for us: benjaminrushinstitute.org.
I am not a web expert, so I have not deactivated anything as this is our live site and I don’t want to blow it up.
Also, can you please explain how to “set your reply as private?” I can’t see any place to do that: “Need to share a file or image? Simply drag and drop any files you wish to share below. … files with the world then please be sure to set your reply as private.”
