Hello! Thank you for all your work on this issue ??
I’m having the same problem. I have not used this plugin before. I upgraded my wordpress site to 4.3.1, then installed the plugin, activated it, clicked the checkbox to turn the plugin on. I have not yet seen any change in access to the site’s pages, the site is behaving the same as it was before installing the plugin. Here are the included names & descriptions of the checkboxes I currently have checked:
Private Site: (This plugin is currently enabled; click checkbox to disable)
Reveal Registration Page: Do not block WordPress standard User Registration page (Advanced Setting: a check mark in this checkbox is recommended)
Where to after Login?: Return to same URL
Check Custom Login URL?: URL must begin with https://sitename.com/ (Advanced Setting: a check mark in this checkbox is recommended)
// Thanks so much!
