I'm helping a community organisation, The Council for Mental Wellbeing, to install and use Koha on Mac OS X 10.4.2. I need a bit of help. :-) The install has seemingly gone fine. All of those missing perl modules are installed (some by force) and we can connect to the OPAC part of the database on port 8080. The problem occurs when we choose the Catalogue menu and then Add Biblio. The following error appears: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, librarian@rcnet.co.nz and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. Apache/1.3.33 Server at 127.0.0.1 Port 8080 So, I've gone to look in the error log and the following error is there: Can't use an undefined value as a HASH reference at /usr/local/koha/ intranet/modules/C4/SearchMarc.pm line 255. [Mon Oct 10 15:07:39 2005] [error] [client 127.0.0.1] Premature end of script headers: /usr/local/koha/intranet/cgi-bin/acqui.simple/ isbnsearch.pl Anyone got any ideas?
