According to https://bugzilla.wikimedia.org/show_bug.cgi?id=63777 Key user_timestamp has been added. It's now missing again after migration. Please re-add. Current keys: PRIMARY KEY (`ar_id`), KEY `name_title_timestamp` (`ar_namespace`,`ar_title`,`ar_timestamp`), KEY `usertext_timestamp` (`ar_user_text`,`ar_timestamp`), KEY `ar_revid` (`ar_rev_id`)
Index restored.
