Hi,

I'm using an awesome RSS Reader called "Fiery feeds" on iOS.
After setting up the API password and doing the first sync (this one works) I never get it to sync again.

According to the App dev, the logs from Fiery Feeds shows nothing wrong.

The only thing I can see Is the following in my error_log_apache:

[Fri Oct 12 21:21:54 2018] [error] [pid 7222] mod_proxy_fcgi.c(834): [client 134.3.0.0] AH01071: Got error 'PHP message: PHP Notice: session_start(): ps_files_cleanup_dir: opendir(/var/lib/php-sessions) failed: Permission denied (13) in /.../freshRSS/lib/Minz/Session.php on line 18\n'

any idea what this could be?
the install check says everything is fine (green)
