I'm trying to setup network blog support so I can host multiple blogs in one install using subdirectories. Everything seems to go smoothly, right up to the point when I enable network blog support and have to re-login in. Instead of a getting a login page, I get a page "Error establishing a database connection".
Obviously there is not issue connecting to the database, since the initial install went fine. If I try to go to the wp-admin directory, then I get an error "One or more database tables are unavailable". I enabled repair and tried repairing, but that fails with error that the tables don't exist (i.e. de_2_posts, de_2_comments, de_2_links,...).
I'm tempted to create those tables manually to see what happens, but I shouldn't have to.
I can turn multisite support off and everything works fine as a single instance, so this is not a database connection issue. I do have control over the server, but I am not installing in the root directory. The install URL is blog/de/
