Multisite with existing subfolders

Go to Super Admin > Options – Registration Settings – Banned Names = names of subdirectory folders with WP installs
e.g. if you have actual subdirectory sites at https://www.example.com/site1 and https://www.example.com/site2, include site1 and site2 in list of Banned Names

@mercime I had thought that banned names = userID or usernames and didn’t think it was also applied to subfolders. I will give it a try. Thank you for your reply.

Hi intimez and mercime!

I was wanting to do the same thing, do my site in wordpress, then for categories which need a more complex CMS use another CMS in that folder, that should work right?
i.e. wordpress in mysite.com so mysite.com/travel and mysite.com/insurance are just wordpress categories.
But mysite.com/shopping I want a different CMS in there, is there anything else I have to do? so it doesnt interfere?

So I presume if mysite.com is a WP blog (with or without multisite), you should be able to run other CMS in mysite.com/cat1 and mysite.com/cat2 right?
I think this may work on the first / main domain, as if the wordpress install files are physically in the folder which hosts your mysite.com domain, then I can’t see why you can’t put another cms in folders mysite.com/cat1 etc … if this is another network blog mapped to that main install with a domain mapping plugin may be more complicated

P.S. A bit more complex if I would probably like the mysite.com/shopping section to have its own blog at mysite.com/shopping/blog so would really want the Nested Paths for Multisite! any idea how to get this to work

cheers!
