Hi Marilyn,
Dunno if you solved your issue but … Did you ?
I got the same problem today after i tried to create a child them for CherryFramework default (free) theme. I’ve spend all my friday trying to find a fix … nothing.
Same error message on this site here :
I’ve read in a post that after a site migration, some less.cache files should be deleted in the theme folder .
It didn’t work for me. Anyway, i work on a fresh installed site (no migration).
I keep on searching …
