After several days of newsreading w/o any problems,
I suddenly got an "Internal server error 500 ..." when updating manually.
(http://www.example.com/selfoss/update)

It's version 2.4 with sqlite database and about 12 feeds and ~1.300 news overall.
What went wrong?

Had the same problem with an earlier version (2.3) some days ago.
Only way to get things back to work, was a complete reinstall.
(I would love an export-feature to easily reimport feeds after repeated clean install...)

edit:
although I get this error, feeds are still updated!
no hints in default.log either...
