Wow, this is
our issue too..
We have active site: https://www.kamilaharrishome.com
and “development site” (for playing around so far to learn..)www.kamilaharrishome.com/dev/
If I understand the terminology correctly, our development site is a “subdirectory”.
However elsewhere in this Forum, it seems to be advised to use a “subdomain” location (www.dev/kamilaharrishome.com) for a development site, rather than a “subdirectory“.
Does it matter much/is it important (also for relative neophytes)?
