Internal server error - RounCube 0.8.1

[youhost]

I've installed Roundcube-CardDAV 0.5 on my CentOs 6.3 x86_64 vmware server with cPanel WHM 11.32.5 (build 10) and roundcube 0.8.1.

When I try to connect with a owncloud installation using:

https://server/remote.php/carddav/addressbooks/username/ https://server/remote.php/carddav/addressbooks/principals/username/

https://server/apps/contacts/carddav.php/addressbooks/principals/username/ https://server/apps/contacts/carddav.php/addressbooks/username/

With all strings I have a generic internal server error.

Do you know about incompatibility of your with roundcube 0.8.1? Also I have Curlssl installed as php module, so I had to cancel your check on Curl activated. But as Curl ssl includes Curl, I think it shoudl work...
