I've been running Arch Linux, latest maintenance level.
After the recent update to QT 5.11, deleted or read feeds don't get removed from the database anymore.
To make it a bit more clear:
- I read a feed or flag it read, then that feed changes it look from bold to normal font style
- I restart QuiteRSS and those feeds appear unread again
- Feeds previously deleted (they appear in the "Deleted" folder!) are shown again after restart of QuiteRSS, too
To cut it short: QuiteRSS keeps updating/downloading the feeds, but doesn't remove/delete any of these.
I even recompiled QuiteRSS, to no further success.
