blank "options" adding Content & Content Around Image

Permalink
Hi-

This just started happening today: whenever I go to add either Content or Content Around Image blocks, the options dialog pops up--but it's completely blank.

The only thing I did today was update update the add-on "Area Splitter".

Since I'm bewildered, I'm posting "generally" here, in case it's *not* the Add-on. Hope that's ok.

(I did go into my cPanel's file manager and there are no files in my /public_html/blocks folder. Is that right? They're in the /public_html/concrete/blocks folder, though.)

Well...I saw another post that helped: I made a new test page and everything was fine--so are most of my other pages.

Though I know how to fix it now, I always feel better knowing the "why".

Anyone else have this happen and/or know what the root of the problems is?

Thanks!
