Hi JonRadio ??
Same problem with a new WordPress installation.
It’s a WordPress 4.2.2 avec with the evolve theme.
Only 3 addons (Akismet, Hello Dolly and jonradio Private Site).
I’ve checked the box “Custom Login Page?” and I fill the “Custom Login URL” and when the informations are saved via “Save Changes”, the box is then unchecked and the URL is blanck. Have I to do it manually in the DB?
