Openfire Openfire Support

When I hit pages like DB Access or STUN server, there is nothing.
They used to work in the previous version.

What is necessary to get this to work, like in the previous version?

Figures, the upgraded Openfire still used the old version’s plugins directory as it went from 32bit to 64bit.
Deleting plugins and reinstalling them fixed this issue.
Not sure why the new 64bit version keeps pointing at the old 32bit version’s plugin directory though.
