We recently upgraded to 10.1 and all of our active groups are on Social theme. We have just a handful of groups that have been "archived" that are still on Enterprise. These groups are not used, but we haven't deleted them yet for various reasons.
The problem I am seeing is that every few days I get a new notification about an error in the the formats.less file.
There is no semicolon at the end of line 261.
I am trying to figure out how to resolve this error. I don't see how to edit the Enterprise Site theme to get to that file to fix it. I thought I could just change the file in the filestorage. It is easy to find the file and make the edit. But the notifications return even though that file doesn't have the error any longer.
Can someone tell me how to fix this without having to delete the Enterprise theme?
