Hi Vaj,
It doesn’t seem likely that there would be a difference between logging in on an admin account vs non admin, because the plugin doesn’t take into account whether or not the user is an admin.
My suggestion, which I have mentioned in a previous message, would be to make sure that visitors are logging in from the homepage. Quote from above:
One important point to note is that when the password is first entered in, this should be done on your homepage (eg https://www.yoursite.com) as opposed to a subpage (eg https://www.yoursite.com/books/mybook). If you enter the password on the homepage, you will have access to any URL that begins with https://www.yoursite.com. If you enter your password on the subpage example above, you will have access to any URL that begins with https://www.yoursite.com/books/mybook. If you then tried to go to https://www.yoursite.com or any other page, you would have to enter the password again.
If this doesn’t resolve the problem, would you consider setting up a WordPress admin account on your site for me(you can create a temp admin account). If you are willing to do this, please email login credentials over to info at clevelandwebdeveloper dot com.
This is all assuming that I am able to recreate the problem when I test it out. If I’m not able to recreate the problem (ie if I login once and it works perfectly for the whole site), I won’t be able to troubleshoot or solve it.
Good luck,
Justin
