Client error on live server

Hi all,

We are encountering an error in our live Tess application when it is being used directly on the live server. It seems to be specific to doing a constituent search and is not happening on the end user computers.

I've tried resyncing the local impresario files and it hasn't resolved the issue. This error is very unfamiliar to me and I'm not sure where the problem is. Has anyone seen it before? Does anyone know of a quick fix?

Windowmenu: nvo_rest_client
Object: nvo_rest_client
Objectevent: uf_encode
Line: 1
Error Code: 32
Error Text: Name not found calling external object function urlencode at line 1 in function uf_encode of object nvo_rest_client.

Thanks!
