Thread:Project:Support desk/Database error: "1054: Unknown column 'rev sha1' in 'field list' (localhost)"/reply (3)

I'm running update.php to update mediawiki 1.15.1 to 1.21.1 on my laptop. I changed MySQL user to root at Localhost.php.

During running the update.php, there is a error 1054: unknown colum 'rev_sha1' in 'field list'(localhost).

The step where error happened was "batch conversion of user_options: A database query syntax error has occurred.

I appreciate it if anybody could help me to solve this issue.
