I’m running 1.4.4 and still getting the “Catchable fatal error: Object of class WP_Error could not be converted to string in…..wp-includes/wp-db.php on line 488” whenever I click on the “blog” link with-in the group. I created the blog added an avatar, set member permissions, etc. with no problems.
When I check the box “redirect to blog” in the admin panel I get a new error after clicking the blog tab
