Error on eB Web.

Hi Everyone !!

I have just Installed eB 15.6.1 Web Server and set up a new site. Despite I have not installed "eB Sharepoint References" when I open any document, in relationships section under the name of "Sharepoint Links", I got this error:

ORA-06550: line 1, column 7: PLS-00201: identifier 'EBPSP_GET_OBJECT_COMMON' must be declared ORA-06550: line 1, column 7: PL/SQL: Statement ignored

How can I avoid this ??
