@n-bely: Go to => Appearance => Customize => Additional CSS and add the following CSS Code.

/* To remove the search field */

.site-search {
	display:none;
}

/* To change color of prev and next */

.nav-previous a, .nav-previous span, .nav-next a, .nav-next span  {
	color:#fff !important;
}
.nav-previous, .nav-next {
	border:1px solid #fff !important;
}

/* To remove home >> uncategorized >> oil paintings(Breadcrumb Option) */
Go to = Appearance => Customize => Theme Options => Breadcrumb => Uncheck the option “Check to enable Breadcrumb”

To edit the footer text
Go to => Child Theme Folder => Create a New Folder “components” => Inside components Create another Folder “footer” => Now copy and paste site-info.php file from the parent theme folder.
Now you can edit the site-info.php file to edit your footer.

Let me know if this works out!
