I already re-installed onto a new server. I was only testing .. If I do reproduce I will make sure to provide stacktrace. I do appreciate you looking into this. I will make sure in the future that I can provide more details.

I reviewed my code and my plugin is automatically bringing the user to the new post page via ajaxify.go().... It appears that when you go directly to a new post the unread notification associated with this is automatically marked as read.

Thanks for your help.

RESOLVED

If anyone else sees this thread... Don't be the american who thinks the default should be en-US....

It appears that the nodeBB default language was set for en-GB

If you need to adjust the language default setting:

Go to your NodeBB ACP (admin control panel) => General => Languages

It appears that if you have long thread and you use back navigation on browser it highlights to show you the last post you clicked.
