Hi Dre, 🙂

To change this, simply replace the previous snippet by this one in your website:

/**
* Hide menus and after-content in register page
*/
.registration .grimlock-vertical-navigation, .registration .grimlock-header, .registration .after_content{
	display:none;
}
.registration.grimlock--navigation-fixed-left #site{
	margin-left:0px;
}

To add this code snippet to your site, we recommend that you paste it to the Custom CSS panel of your WordPress Customizer. Just go to your dashboard and navigate to “Appearance > Customize > Additional CSS”.
Pasting your code snippet there should do the trick for you.

Also, it’s important to remember that we share snippet only to solve issues with our theme. Any further request for CSS snippets will have to be part of a defect that needs to be fixed urgently. No snippets will be shared otherwise.

Thank you for bring these new issue to our attention. We’re glad to answer any question related with the setup of our theme.

However, it is very difficult for us to provide the best support possible and to keep track of issues and their resolution if so many questions are asked in the same topic.
Moreover, it’s easier for us to share the resolution for a single issue with other members of our community facing the same problem.

So, could you move your other question into a different topic, please? One question = one topic.
By doing this, you will be making a great contribution to this forum, and we thank you very much for that! 🙂

Thank you.
