Widgets on every page

@jessup573: Hello there,
Go to => Appearance => Customize => Additional CSS and add the following CSS Code.

/* To have the social and gallery widget only the main homepage */
body:not(.home) #footer-instagram #catch-instagram-feed-gallery-widget-4 {
    display: none;
}

/* To remove Archive text from Blog page */
.blog.absolute-header .site-title a, .blog.absolute-header .site-description {
    color: #000;
}
.blog.navigation-classic.absolute-header .site-header-menu .menu-wrapper .nav-menu > li > a, blog.absolute-header .site-header .site-header-main .site-header-menu .menu-inside-wrapper .main-navigation .nav-menu > li > a:hover, .blog.absolute-header .site-header-main .menu-social-container li a, .blog.absolute-header #primary-search-wrapper button {
	color: #000 !important;
}
.blog .below-site-header .custom-header {
	display: none;
}

To delete blog posts you didn’t write
Go to => Dashboard => Posts => Select and Move to trash.

I am afraid the Tik tok icon is not available in Font Awesome that the theme used for icons.

Can you let me know what kind of graphic image you are trying to add to the main page?

Let me know if this helps you out!
Kind Regards,
Skandha

@jessup573: Hello there,
To make the code work for the Video widget as well.
Remove the text #catch-instagram-feed-gallery-widget-4 from the code I provided above.

The option to add a logo over the Header Image is only available in pro version of the theme. I suggest you to upgrade to pro. You can check out the additional-features available in pro version of the theme.

Let me know if this helps you out!
Kind Regards,
Skandha
