I'm running custom firmware 3.10. The EPG in the web interface does not show any listings (screenshot attached) but works normally when viewing it on the TV screen. I cannot see any settings to adjust to try to fix this. Can anyone help?
Have you checked which favourites group the EPG settings in the Web-If is set to?
If it is set to a favourites group that is now empty that will achieve a blank Web-If EPG identical to your screenshot.
I find this happening quite a lot on one of my machines (no favourites involved). What I have to do is go into Maintenance Mode and run "clear persistent EPG data" from the Telnet menu. After that it will need a bit of time to reload the EPG data from the broadcast stream.
