DrDave: I recently moved my wpmu installation between hosts. In doing so I inadvertantly went from MySQL 5 to MySQL 4.
That then caused problems about autoincrement flags on the sk2 tables... so I deleted all the sk2 tables reasoning that if the tables were missing then sk2 would recreate them with the right autoincrement flags.
I discovered that its the presence of the sk2 options that determines whether sk2 knows to create those tables, and that I'd need to delete the options from each blog's option table to get sk2 to rebuild the missing table.
It seems I can go through each of the many blogs and click "Reset all tables", but is there a way to mass-process this option for every blog?
