Editing LiveTV Channels or Change Guide Data ending in http 500 error

[peter2020 2]

Hello.

I faced the issue that I cannot change any Live TV Channel or Edit Playlist anymore.

Emby Clients got a http 500 error from server with response:

"The 'meta' start tag on line 8 position 8 does not match the end tag of 'head'. Line 10, position 5."

When looking into embyserver.txt I found:

Any suggestions how to solve?

Thank you in advanced.

PS: When trying to change any channel, I got the blue spinning circle and the http 500 error occurs.

HI, one of your xmltv sources is not returning valid data. Currently when this happens, our editing features may not recover very well. This is something we're working on improving.

In the meantime, just remove the invalid xml guide source and that should get you squared away.

Hi Luke,

Thanks a lot for looking into this. Indeed, that was the problem. I had a cronjob grapping data from webgrapplus and one of this guides / sources had a problem and the xml file was not correct.

After fixing this and refresh livetv guide data task, everythink is working again. Thank you!
