I'm following the guide here and have a login page created as described. The link from lost password simply goes to /login/?lost-password=true which simply gives me a "page does not seem to exist" error.
My site is so far pretty simple so I doubt I've done something too crazy that would disable this. What am I doing wrong?
Please try to deactivate all plugins except Meta Box, Meta Box extensions, switch to the default theme of WordPress (Twenty Twenty), and clear the cache then check this issue again.
