Thank you!
I guess it was one of the plugins. I tried the permalinks but that didn’t help. But after I deactivated all the plugins and activated them one by one it worked! I totally forgot about that. I haven’t installed any new ones but maybe it was an update or something.
I works now anyway. So thank you!
Oh, sorry!
Yes, I do. And I tried as you say to switch to Twenty Twelve but it didn’t help. Still can’t se my posts one by one, but the main page is fine.
