Not sure what happened. I've been running ntopng-enterprise for a bit, but this morning when I went to upgrade the system I saw there was an update to ntopng-enterprise.
It was running version 5.7.230811, updated to 5.7.230812, but now the web ui for it shows I'm on a really old 5.6 release. Under firmware, both ntopng and redis are showing (misconfigured) after them.
It seems to be working, just reporting it's an old version.
