Hello. I installed DNN on interserver.com. They offer only DNN 7. I installed it and it worked. Then I upgraded to 8.0.4 and then to 9.2.2, both successful. The initial website works.

Then I created a new portal, default template, domain, current administrator as user. The portal shows in the list of sites. But that is it.

If I browse to it I get 404

If I try to go to settings or pages nothing happens

If I try to delete it, it works

I tried then to do the same on Portal 0. I can browse but it will not open site settings or pages. If I browse to it, I can get to site settings but the tabs information is incomplete.

Site Info, Site Behaviour-Default Pages and synonims are empty

Other tabs/sub-menus work ok.

On the empty ones I get a red bar "There was an error retrieving your content. Please check your internet connection"

Could anybody help me with this? Thank you
