Hi quantentunnel, sorry for the late reply!
I tried to reproduce this issue, but i can't. Export is working fine here (also with the upcoming 1.3 Final release), so i'll set this to No Bug for now.

If you keep experiencing issues with this, please let us know!

I don't know what caused the issue, but it still is present on my end and I still couldn't find a way to fix it.

I hope the update to 1.3.0 will do something good, since installing 1.2.3 over the existing installation made no change at all. I refrain from uninstalling and reinstalling right now because I don't have much time to redo all the channel ordering and tweaking, in case the database won't push settings back to the TV server after a clean install thus leaving me with a lot of work I can't bother to do at the moment.

Checking the MySQL database didn't show me anything unusual as well (in sense of duplicate or corrupted entries) so I'm quite lost here.

For now, I've made a dump of the database, just to be safe.
Can't wait for the release of 1.3.0 Final to get my hands on it to try it out!

Do you also get the error when you use the (tip ) BackupSettings plugin?

 

[quantentunnel]

Using the backup plugin made me find the culprit finally!
It was two entries in the radio channels table that lead into the void (must have been leftovers from one of the many scans I did setting MP up), leaving the exporter clueless and unhappy. The backup settings plugin threw an error telling me the IDs of the entries. Too bad the built-in exporter didn't do this.

Anyway, after I truncated the radio channel table and did a fresh channel scan (luckily I didn't bother to sort radio channels in the first place) the exporter worked like a charm. I'll keep the backup plugin for the migration to 1.3.0 though, just in case.

Thanks for the tip, HomeY! Can be closed/archived.
