CUNY Academic Commons

I (Marilyn) regularly post on two sites -https://historyprogram.commons.gc.cuny.edu/ and https://mabam.commons.gc.cuny.edu/. Today, I am having problems posting on the https://historyprogram.commons.gc.cuny.edu only. I cannot use any of the options in the publish area (see screenshot) and I cannot Add Media.

I can do these things on https://mabam.commons.gc.cuny.edu/.

I thought perhaps this was a problem with my PC, so I shut it down and restarted. No dice. Now I find I am having the same problem using my Mac. I am using different browsers - Chrome on the PC, Firefox on the Mac.

I have tried logging in as MWeber and as marilyn_super. Neither solves this. I can post, but I cannot use these features (and I love to schedule posts and very frequently need to add media.)

The theme is ColorMag. I've been using it for a while. If you think the theme is the cause I have no objection to switching it to Divi, which I use at https://mabam.commons.gc.cuny.edu/

I'm leaving the priority as Normal as I assume the problem is mine alone. I'm fine for now as long as I don't need to use add media or delay a post. LMK your thoughts and questions.
