Thanks but this was a general question.
It might be useful to have this information somewhere under settings.
I ended up finding which site was the one I was looking into but it’s a pity hat I had to guess instead of reading this somewhere.
I just spent quite a bit of time trying to figure out why one of my test websites was different from the other, not remembering if I had installed a site from the library, resetting the database to no avail, etc.
Don’t get me wrong, GP is great, the sites are great but this is sooo different from the child themes I’m used to! Don’t know what is stored where… file? database? I’m new to GP and I may be a bit thick too, but I find this system very confusing. I haven’t found a page explaining how they work. Bad search?
