Thank you for the quick response. The fact is that my site is for a Russian. So, only Vkontakte is actual for us. I used another plugin, WSL, but it conflicts with my security setting (“hide login page”), in fact, it displayed my hidden url for each. Your plugin is ideal in this regard. But WSL saw email automatically. Hence, it is possible. That plugin required a secret application key (i have it), but your plugin requires id only. Maybe the problem is because of this? Not enough field? Perhaps you have ideas or recommendations for adding a code? Anyway, I’m grateful for the link, I’ll try to figure it out.
