Thanks Chris, but... it is the latest version of Opera (34, both .deb and win)
When I check Opera 34 on Windows I see no SSL error.
Solved -- or at least I've maybe got to the bottom of this. I now have Opera running on Ubuntu, Debian and Mint desktops, by forcing the following certs: * ISRG Root X1 * Let's Encrypt Authority X1 (IdenTrust cross-signed) * Let's Encrypt Authority X2 (IdenTrust cross-signed) * DST Root CA X3 It appears that the Koha/Let's encrypt certificate will never work on WinXP (we still have three work spaces, unfortunately) except with Firefox (so Opera, Chrome and IE don't work.) This is apparently a Microsoft problem, as the Let's Encrypt "countersigner" needs NameConstraints which MS have not backported to XP and Let's Encrypt apparently can't do without it. Full details at <https://community.letsencrypt.org/t/help-needed-windows-xp-support/8756> Maybe it's not too important -- WinXP only has about 11% market penetration according to <https://www.netmarketshare.com/operating-system-market-share.aspx?qprid=10&qpcustomd=0> and Opera is not a prevalent browser -- we just like it for it's speed and clean layout, but our users/cataloguers rarely need the Koha wiki. So I can live with it until we can convert the boxes to Linux. Thanks for the responses -- Paul
