Hi, we are migrating server from ola.bida.im (koha version 20.11.03-1) to bib.bida.im (koha version 23.11.02-1). The search seams ok, but when we enter in bib-intra.bida.im we have an 500 internal server error with this message log in intranet-error.log [Fri Mar 01 10:17:37.076210 2024] [cgi:error] [pid 233068] [client 46.255.84.17:65195] AH01215: [Field userid is not valid (probably not unique)]: /usr/share/koha/intranet/cgi-bin/mainpage.pl, referer: https://bib-intra.bida.im/cgi-bin/koha/mainpage.pl [Fri Mar 01 10:17:37.223900 2024] [cgi:error] [pid 233068] [client 46.255.84.17:65195] End of script output before headers: mainpage.pl, referer: https://bib-intra.bida.im/cgi-bin/koha/mainpage.pl can you help us? thanks -- jops GPG keys available via keyservers https://keys.openpgp.org/search?q=jops%40riseup.net https://keys.openpgp.org/vks/v1/by-fingerprint/32D254CF0B219482E28909CDC2FF3...
