Hey pinkylips,
I found the problem after someone else sent in the details I needed to figure out when this was coming up. The menu item permissions were not being initialized for new installs of the last update that I just released so it was causing WordPress to not allow access to the settings page. I have re-released the fix for this in the latest update, version 4.16.17. Please download the new update and let me know if that puts the Plugin Settings options in the admin menu for you. If the new release fixed the permission error for you please update your review so I know it’s working for you ??
Aloha, Eli
