B26 crashed 5 times tonight

Hmm, Unfortunately I can’t really tell if the error message includes the needed information. I think I’ll just leave things as they are, it won’t check the port on your system.

Do you mean static web pages? That would be Apache.

By “Enterprise” you mean Panorama 6? Panorama 6 does not have a built in HTTP server. So you MUST use Apache, which then uses Apple Events to communicate with Panorama 6 Server. (Panorama X Server also has an option to use Apple Events, but it turns out that they don’t work with anything newer than macOS 10.12 Sierra.)

It’s no problem to run both Panorama 6 Server and Panorama X Server on the same computer. There’s no adjustments needed, there are no conflicts. One uses panorama.cgi and the other uses panoramax.cgi.
