HTTP 500 error and no logs in nginx error.log

[skibbipl]

Issue details

I've updated wallabag to latest git version and I'm getting http 500 errors while trying to access:

• https://wallabag.domain.tld/config
• https://wallabag.domain.tld/settings
• https://wallabag.domain.tld/archive/list

The issue is that nginx error.log in empty! No errors at all. Even enabling debug doesn't suggest what's wrong.

Environment

• wallabag version (or git revision) that exhibits the issue: 2.0.4
• How did you install wallabag? Via git clone or by downloading the package? git pull origin master
• Last wallabag version that did not exhibit the issue (if applicable): 2.0.0
• php version: 7.0.5-3
• OS: Debian testing
• type of hosting (shared or dedicated): cloud (dedicated)
• which storage system you choose at install (SQLite, MySQL/MariaDB or PostgreSQL): SQLite

Steps to reproduce/test case

Just trying to access mentioned links on my domain.

OK, I just realized, that wallabag keeps its logs in its own location. The issue was related to missing write access to cache dir.
