I guess you mean that hiding the login form with Accepted/Declined Cookies group I'm golden. Sorry, but I'm not!
There are not ONLY two groups (Accepted or Declined Cookies). There is a third one (Not Decided Yet). I need to separate them all three, because actually they have different permissions and privileges. That's (almost) all the fuzz about!
On the other hand, when Not Decided Yet, if registration/login is hidden the user doesn't realizes that actually there is a "site-behind-the-site" (only for registered ones), simply because he doesn't see any way he can become a member. Users MUST see the registration/login button, MUST know there is a registration/login process, but he is not entitled to this because he hasn't accepted cookies/policy yet. He wants to, he doesn't know how. Oh, don't tell me it is written in the policy in the cookies banner. Just tell me, what is the user percentage that actually reads more than 2 lines? And yes, I don't want to loose these users.
So finally, I need three states: Accepted Cookies, Declined Cookies, Not Decided Yet. The first two from your plugin work perfectly. Actually they are only one, but they 're OK.
Accepted Cookies: Registration/Login shown
Declined Cookies: Registration/Loginh hidden
Not Decided Yet: Registration/Login disabled style, tooltips, onclick messages/alerts that cookies/policy has not been accepted and the whole story why the user should accept cookies/policy, etc.
That's it...
Is it possible?
Thank you for your patience....
