@A-Former-User said in user manual outdated.:
it also doesn’t work when I click proceed to npp-user-manual.org(unsafe)
I could open that link without problems in Google Chrome, it seems the certificate is valid since October. However, www.npp-user-manual.org was giving the same warning you saw… I cleared my browsing data, including ‘Passwords and other sign-in data’, restarted the browser and now it working proeprly. It happened the same with Firefox and I ‘fixed’ the issue by clearing all my browsing data and restarting…
I guess there must be some place in the network and/or in our browsers that is keeping our local certificates from updating?
