I forgot to mention that the popups don't seem to work either. I get this error message when I try to use them:
Apologies! An error has occurred. You may be able to continue, but some parts may not work properly.
Error: macro <<popup>> does not exist.
And then there's a bunch of markup code...it seems to be the same on the template. I'm using Firefox but I tested it on Brave (Chromium based browser) too, and I got the same basic error.
