Use a white page for login form ?

I’m not sure what you are asking for, is there any examples that you can show us to help us better understand? You can style the default login screen with CSS: https://codex.www.ads-software.com/Creating_Admin_Themes#Change_Log-In_page.27s_style

Thanks for your answer.
I mean, if memebers will login on my url then he see my background, header and more…
What i want i login form without backgrounds, header… Only a blank or white page with the login form. (textbox, buttons)
I have the plugin user meta pro. I can make the login with this but not the white page…

Alright, you should look into the link I gave you above. That will show you how to customize the login page for your site so that you can make it display however you wish.

Hello,
Thats pretty good! i will tried it, thanks..
There is now only a problem.
I want to set on a page a login form from the internet browser self.
Only for members who have buy my products (sample)

I think there may be a slight language barrier, pcwolf. But if I’m understanding correctly, you want a login form on the browser’s interface? If so, that would require developing some sort of plugin for your browser – which I can’t really help you with. Communities dedicated to the browsers you wish to target can help you there.

I know, it’s not easy to set the browser’s interface.
But i can with user meta pro approval the account and members can view it.
So there is no a problem more.
Thanks.
