The data should be migrated. Show some logs, there must be some errors.

There was nothing in the logs at all, even with debug on ?!?!

Tried in an incognito window in case anything was cached, still the same.

I've reverted back to an older version which is working fine (stable 4.2.1)

The updates for the docker image are done weekly, so I'll test again in a week and see if the issue is still there.

Thanks

Tried this again this morning, again absolutely NOTHING in the logs. It's as if clicking on the button in the web interface does nothing at the backend.

I even enabled debug logging and put http and epg in the trace subsystems options....

Still nothing.....

But, when I exited TVHeadEnd to go back to 4.2.5, I did see this.....Not sure if the 3rd line from the bottom is relevant.....

I might be stating the obvious here, but you'll only get a complete log by using the debugging options.

'--trace epggrab' - https://tvheadend.org/projects/tvheadend/wiki/Traces

Could you show me old (original) config - directory <CFG>/epggrab/otamux ?

The fix should be really simple - remove this directory or retrigger the scan for all muxes, but if you like to know why the old files are unuseable, follow my instructions.

I removed the mentioned directory and made a rescan of all (active) muxes.
Epg grabber is fine again.
Forgot to copy config directory before deletion - sorry.
Is there a way to avoid this issue in future?
Thanks!

It was a bug in master, it's fixed now.
