I was using my development server which has been used previously for various other projects. I tried starting again with a clean installation of Debian 11 on another machine. This time the Koha installation worked flawlessly. So it seems the original server was misconfigured in some way that caused the problems below. -----Original Message----- From: Koha <koha-bounces@lists.katipo.co.nz> On Behalf Of Thomas Daly Sent: 27 February 2023 14:41 To: koha@lists.katipo.co.nz Subject: [Koha] 500 Internal Server Error I'm finding that the Koha instance's intranet site is crashing with an Internal Server Error. It first happened when I tried to change the superlibrarian's user ID. I couldn't recover the system at all, and had to delete and re-create the instance. It has recurred in the installer when selecting the language.
