Hi all, I was running Koha Plack on OpenSuse (using CPANed libraries), and I noticed that creating a new authority would take me to /cgi-bin/koha/authorities/detail.pl?authid=1, which then spat out an error in my logs of "Subroutine build_tabs redefined at /path/to/koha/intranet/cgi-bin/authorities/detail.pl line 56." After that, it became impossible to create a new authority via /cgi-bin/koha/authorities/authorities.pl. Seemingly because the build_tabs subroutine had been redefined to be incompatible with authorities.tt. I noticed that this only affected my OpenSuse Koha. It didn't affect Debian or Ubuntu. That makes me think that it's due to an issue with the Plack libraries being used. On Ubuntu I was using 1.0047, on Debian I was using 1.0042, and on OpenSuse I was using 1.0039. My guess is that it's an issue with the older library, but I really don't know. Wondering if anyone else has encountered this particular issue. Same Koha code running on each OS, but yeah. the OpenSuse was having issues that the Debian/Ubuntu didn't.
