A site will throw mysql warnings before the comms module is finished being configured.

In the process of configuring the comms module the following error was displayed while configuring the content types:

user warning: Table 'democomms.og_uid' doesn't exist query: SELECT n.title, n.type, n.status, ou.* FROM og_uid ou INNER JOIN node n ON ou.nid = n.nid WHERE ou.uid = 1 AND ou.is_active >= 1 AND n.type IS NULL ORDER BY n.title in /var/www/hackbloc.org-5.x/www/includes/database.mysql.inc on line 174.
