Same/similar error as reported here, but without using any joins: https://datatables.net/forums/discussion/39387/fatal-error-call-to-a-member-function-insertid-on-null. Full error:
PHP Fatal error: Call to a member function insertId() on a non-object in /var/www/html/new/includes/editor/php/Editor/Editor.php on line 1601
Upgrading from Editor 1.5 to 1.6, haven't been able to pin down what's causing it yet. The referenced post had to do with Mjoin, which I'm not using. Trying to troubleshoot, but I don't think I can use the datatables debug area since it's server-side scripts.
Thoughts?
