Seafile.ini not found

After performing an upgrade from 6.2 to 6.3 seafile (i first upgraded/updated my Debian os to the latetest) does’n t run anymore.
A fresh reboot doesn’t solve it and when i try to start seafile & seahub.sh seahub throws …/installed/ccnet/seafile.ini not found at me.

Anybody know how i can find the cause of this?

Kind Regards
Gerard
