I had the same problem when installing MU on 3.0, but didn’t think it would mess up things.. i was wrong, only getting 500 internal error when going to sub-blogs. (Wildcard is active on the server)
So i have gone trough the database now thinking it should be some thing that’s happened there. And found some odd things(think there odd at least..).
In the wp-options – _transient_dirsize_cache line the url is messed up when pointing to the “blogs.dir”. It’s saying:
a:1:{s:88:”/customers/domain.se/domain.se/httpd.www/wp-content/blogs.dir/1/files/”;a:1:{s:4:”size”;b:0;}}
I don’t know if it’s suppose to be like that but in my eyes it looks wrong.. Any one that’s better then me that have any thoughts?
EDIT: Can also add that it seem to be the only place in the database that points to blogs.dir
