Roundcube Addressbook with Kolab

[Alexander Schröter]

Hey I followed the instructions in the wiki, but I am getting this error.

I am not sure if this matters because I don't think the file would be in that 
directory anyway but I have Kolabs apache running on a different port and 
roundcube is using my systems apache. So there might be an issue with an 
absolute path somewhere (yes/no/maybe?)

Any thoughts?

But I do get the following errors:
