500 Internal Server Error

After an update I get the error at the login xxx/scriptcase/devel/iface/login.php: 500 Internal Server Error

What is wrong?

In the apache2 error.log:
[Wed Dec 28 14:13:24.753059 2016] [core:notice] [pid 1636] AH00052: child pid 2705 exit signal Segmentation fault (11)

Please, help!

Appearantly some update went wrong. I would recommend trying to contact SC support as your projects might now be in risk if you haven’t got proper backups. IMHO best way is to re-install. If you haven’t got backups you should first create a full binary backup just in case so you might be able to recover from your old projects. You need the sqlite database for that and the worker project directories.
