-Status: Feedback +Status: Bogus The version of Roundcube does matter. The 0.8.2 release was improperly using the isError() method. There are two $this->db_handle->isError() calls in ./program/include/rcube_mdb2.php. That has been removed in master. Please open a ticket with Roundcube to get them to change the calls to MDB2::isError().
