How to view logs/debugs for TT-RSS back-end?
I mean, I know system log in web GUI, but it shows events related to front-end, client-related issues. Same for nginx logs.
What if I want to check events related to RSS feeds?
My problem is - one of the feeds show error " LibXML error 23 at line 164 (column 258): EntityRef: expecting ‘;’ ". It happened before, and resolved itself after a day or so. I guess, this is because some entry in RSS feed contains symbols, that breaks libXML parsing. As soon as the RSS XML file gets updated to remove this entry, feed is parsed as usual.

that depends on how you run it. docker-compose logs etc.
you’re mistaken.
i dunno how tt-rss backend logs would help you with libxml errors. you can always use feed debugger from the frontend (or via update.php), although it would give you this same error message.
What is this? Is it the message box that appears when I click for details on feeds that cannot be updated?
How to do that?
Is there a way to debug libXML library? I know what @fox is going to tell me, I’m asking other users, who may happen to stumble into this before.

there’s plenty information on feed debugger etc. on the wiki and this forum so i’m going to refer you to the search function.
imo both you and those hypothetical other users would have more luck discussing libxml in a more appropriate place i.e. where a libxml developer might answer.
although i’m not even sure what’s to discuss here, feed publisher should fix their malformed document, that’s pretty much it. the error is clear enough, why would you want to debug libxml further. 
So, yeah. I found problematic entry in feed XML file. My bad is I didn’t figured out that lines and coloumns in error message are for XML file. I thought this was related to some libXML internal files.
Most probably the issue is & symbol in URL, which must be replaced with & ;
I don’t see an easy way to do this on my side, most probably, RSS XML feed maintainer must implement some changes to replace this symbol in URLs. Thanks for help.
