Hi Leo,
A change was made to default the "/frame" server to disabled a while back, you may have created a new profile and just encountered the change.
The "/panel" server is faster and puts a much smaller load on your server and the network, but as you see, the "/panel" server requires WebSockets, if you have more than a few "live" items on your panel.?
If you want to reenable the "/frame" server, you can do so in the JMRI Preferences, Web Server page.
Regards,
