It throws lots of warnings saying $allowedentitynames is null and function in_array cannot accept null as second parameter. My manual fix is to add the following check before return: if (!$allowedentitynames) return ""&$i;""; if would be nice to have this investigated and fixed." defect (bug) closed normal 6.2 Formatting normal fixed has-patch needs-testing
