wp-members – register when connected

Hello !

I’ve got a little problem and I think you can help me.
I have to make a private zone for my website, but the only one that can create account is the admin. So I’ve create a page where only the admin can go (with the plugin User Specific Content).

But the problem is that I can’t create an account when I’m connected, the shortcode “[wpmem_form register]” only propose myself to disconnect or to go to the home page.

And if I disconnect myself, I can’t go to the page to register, because I’m not an admin !

I’m trapped in this situation and I’d like to know if there was a way to fix it ?

Thanks 🙂

Oh and sorry for my english it’s not my mother tongue…
