I am using Nabble to host a small forum at
http://wsprdaemon.org/forum.htm,l but I cannot find a setting in Chrome or Safari which permits me to login using those browsers.
My symptoms are that I go through the login process and return to the forum page but I am still not logged in. There was no 'failed to login' dialog. Chrome says the site is not secure, but changing Chrome settings for the site has no effect.
Using Firefox without any configuration changes, I auto-login with the information stored in my Lastpass account.
