That is not what is happening on my forum.
I am experiencing this issue exactly:
XF 1.3 - Missing/skipping some alerts
I am running 1.4.8 and all of my add-ons are up to date.
Major add-ons include xenporta2, ui.x, post ratings, and Tapatalk. I've got some smaller ones too, but they are field removals, calendar, etc. Nothing that should interact with the alert system.
I run on a VPS.
Thank you for any assistance.
