Annozilla + zope annotation server

Hi,

I just installed Zope annotation server in my VDS acount with unix socket
option. Everything seems fine, except that when i try to send annotations, it
always ends with this : "Annozilla was unable to post the annotation. The
server responded: unable to create annotation on remonte server.

Please let me know what exactly should be done. Any help would be VERY VERY
appreciated.

Thanks.

John
