I did a lot of updates and now I can only access the first Site of my multisite Installation in the backend und in the fronted unser can only see the home side of each multisite.
I don't like to use a old snapshot of the server, because it took me quite a wile to do all the updates.
Could you give me some hints to find the error.
I did following updates:
domain mapping 4.4.1
Yost SEO 3.0.7
Word fence Security 6.0.22
Thanks for the help.
