Hello,
after upgrading and run the update.php in console I get this error:
 
Error 1054: Unknown column 'rev_user' in 'where clause' (localhost)
Function: Editcount::editsInNs
Query: SELECT COUNT(*) AS count FROM `user`,`revision`,`page` WHERE user_id = 1 AND page_namespace = 0 AND (rev_user = user_id) AND (rev_page = page_id) GROUP BY page_namespace LIMIT 1
 
What is to do?
 
Best regards
