We are trying to install the Ranking Block on Moodle 2.7.2 and we are getting the below error. Is the Ranking Block compatable with version 2.7.2? according to the plugin site the version only goes up to Moodle 2.6?
Table 'i850966_mood1.mdl_user' doesn't exist
SELECT

FROM
mdl_user u
INNER JOIN mdl_role_assignments a ON a.userid = u.id
INNER JOIN mdl_ranking_points r ON r.userid = u.id
INNER JOIN mdl_context c ON c.id = a.contextid
WHERE a.contextid = ?
