Hi Alan, These days the best place to post questions is on the Koha chat at https://chat.koha-community.org/ It sounds like you might have a few different things going on here. If Apache can find maintenance.pl but is returning a 500 error, that means that your file is likely missing the execute permission on the file system. However, that also means you're running in CGI mode, which is problematic. You'd need to change over to using Plack mode. The best, most widely supported way of installing Koha is to install using Debian packages on Debian/Ubuntu using instructions like these: https://wiki.koha-community.org/wiki/Koha_on_Debian If you're using a different installation method on a different OS, it'll be harder to set up.

Going to our main Koha page, we get "Internal Server Error" and the URL has changed to "site.org/cgi-bin/koha/maintenance.pl". Apache shows a 500 error trying to find maintenance.pl. Our server folks are baffled. They think they have followed the installation instructions correctly, but we're not able to access anything. I don't know where to look or what to check or how to fix it. Can someone point me to documentation that might help, to a report of a similar problem, or tell me what to look at in order to diagnose and fix the problem? If this isn't a good list for this question, please let me know where to ask. Thanks! Alan Manifold Yeppoon, QLD alan@mashiyyat.net
