https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=29678 --- Comment #23 from Phil Ringnalda <phil@chetcolibrary.org> --- I didn't explain that very well. In https://git.koha-community.org/Koha-community/Koha/src/commit/f7e1559a7944ab... we have the full URL to http://www.loc.gov/marcxml/xslt/MARC21slimUtils.xsl in an include. That fails with [WARN] XSLT::Base: Unknown IO errorI/O warning : failed to load external entity "http://www.loc.gov/marcxml/xslt/MARC21slimUtils.xsl" That URL actually returns a 301 to http://www.loc.gov/standards/marcxml/xslt/MARC21slimUtils.xsl so if you alter the URL in the include to be that, it again fails with [WARN] XSLT::Base: Unknown IO errorI/O warning : failed to load external entity "http://www.loc.gov/standards/marcxml/xslt/MARC21slimUtils.xsl" Then when you see that http://www.loc.gov/standards/marcxml/xslt/MARC21slimUtils.xsl also redirects, to https at https://www.loc.gov/standards/marcxml/xslt/MARC21slimUtils.xsl and change the URL in the include to that URL, you still get [WARN] XSLT::Base: I/O warning : failed to load external entity "https://www.loc.gov/standards/marcxml/xslt/MARC21slimUtils.xsl" It's not a perfect test since the URL isn't available at both http and https, and maybe it falls under one of the cases that bug 12758 didn't cover, not sure. -- You are receiving this mail because: You are watching all bug changes.
