ON: SQL Server 2008 R2
When trying to activate the WP Groups plugin (http://wordpress.org/plugins/groups/), I get Fatal error: Cannot access empty property on the following line (drivers/pdo.php, _post_query() method):
$this->last_result = $this->result->fetchAll(PDO::FETCH_OBJ);
I tried checking for null, empty, property_exists, method_exists on
fetchAll() prior to that line so I could log the query that is causing the problems and none of my checks ever returned false. Could this be a problem internally in the fetchAll() method?
When logging all queries the last one logged before the fatal error is:
12/16/13 19:34:33,788  DEBUG pdo_wpdb - PDOStatement::__set_state(array( 'queryString' => 'SELECT @@IDENTITY', ))
SELECT @@IDENTITY executed without error earlier so I can not say with confidence that it is the culprit.
I've spent a few hours on this and can't figure it out. Any suggestions?
