After I've upgraded the files in my WPMU 2.0.2 install with the WP3.0 ones (following all the steps in http://codex.wordpress.org/Upgrading_WPMU - I'll upgrade to 3.9.2 as the last step.)
I can no longer access the Admin.
When I go to /wp-admin/ to run the network upgrade of the database, WP tells me that the DB needs repairing, and after trying that, it tells me it can't and that:
wp_posts: Table 'dbname.wp_posts' doesn't exist
wp_comments: Table 'dbname.wp_comments' doesn't exist
wp_links: Table 'dbname.wp_links' doesn't exist
wp_options: Table 'dbname.wp_options' doesn't exist
wp_postmeta: Table 'dbname.wp_postmeta' doesn't exist
wp_terms: Table 'dbname.wp_terms' doesn't exist
wp_term_taxonomy: Table 'dbname.wp_term_taxonomy' doesn't exist
wp_term_relationships: Table 'dbname.wp_term_relationships' doesn't exist
wp_commentmeta: Table 'dbname.wp_commentmeta' doesn't exist
*actual database name changed to dbname above.
It's a multisite install so these tables should not be there. They exists for each blog as dbname.wp_1_posts, dbname.wp_2_posts, etc..
What could be going wrong here, and how can I fix it?
