Did you "mysqladmin reload" after re-loading the "mysql" database? Can you see the actual data after connecting with: mysql -uuser -ppasswd mediawikidatabase select * from revision limit 10; > I'm leaning toward a MySQL User permissions problem, but I think I've > ruled that out by getting in using the same credentials with other > tools. > > Any insight?

Also you might need to login as the database supervisor (sometimes called "root") and talk to the "mysql" database and examine entries in the "user" and "db" tables (and maybe "host"). Maybe that didn't get restored as it was before. The best way to re-create the user needed is this: GRANT INDEX, CREATE, SELECT, INSERT, UPDATE, DELETE, DROP, ALTER, LOCK TABLES ON mediawikidatbase.* to 'wikiuser'@'localhost' IDENTIFIED BY 'password'; Please keep in mind that 'wikiuser'@'%' and 'wikiuser'@'localhost' are different users from the MySQL point of view, with their own passwords and permissions.
