I want top upgrade WordPress from 3.0. to 3.1.2 and but my multiple sites (network) does not work. I can see "My Blogs" in the Dashboard-Tab and I see both networks with two directories http://www.mydomain.eu and http://www.mydomain.eu/en but I cannot access the dashboard of the english version. I get a 404-Page not found.
What I did, was intall the new WordPress Version 3.1.2 and then insert the data of the old database. I had some problems with the users table, the first id was duplicate so I couldn't insert the users at the beginning. Then I updated the admin-user and inserted the rest of the users without the first id.
Also I uploaded the plugins and the theme directories and the blogs.dir.
Everything looks fine in the fontend. Except for the Contact-Forms (Informations of the Plugins) and the englisch Version of the site. I cannot reach these sites at all.
The maintenance mode plugin is active, as long as the site is not ready yet.
I was wondering if I have to "downgrade" to the old wordpress version 3.0 again, to get the site working?
Thanks for your help,
