I have set up a multisite network on my root domain. I followed some instructions & added the relevant data in the htacess files etc. It seems fine, but when I go to 'My sites' in the wp admin it is only showing my root domain site. I don't know how to add the others.
I tried adding adding a new site via the network wp-admin but if I add an existing sub-directory I get taken a page saying; Missing or invalid site address. But those addresses are still there & are correct.
Could anyone offer any advice on how I can add existing sub-directories to the network as I really cant even guess.
