Research direction
The error occurs at pnotify.js line 641 in the PNotify.position method when accessing window.opener inside iframes. Investigate whether window.opener is null/undefined in cross origin iframe contexts. A common fix is to check if window.opener exists before accessing its properties. The repository is stale with no recent activity, so any fix would need to be proposed in a new PR.
