I searched for a solution, but so far haven't found one, although I found a bunch of references.

I got the following lines in my koha-error_log;

 [error] [client 127.0.1.1] File does not exist: /usr/share/koha/intranet/htdocs/opac-tmpl, referer: http://debian:8080/cgi-bin/koha/catalogue/search.pl

It makes perfect sense because opac-tmpl is located in /usr/share/koha/opac/htdocs/opac-tmpl

Thanks again,

Marty
