Hi @hansv-jensen

Apologies for the late reply.

Login to your dashboard and go to the Appearance > Customize > Additional CSS and paste the below custom CSS code to make the background of the articles completely white without frame around, to remove related news at the bottom and remove date at the top:

.post-boxed,
.post,
.type-attachment,
.widget {
	box-shadow: none;
	-webkit-box-shadow: none;
	-moz-box-shadow: none;
}
.info-bar .contact-section {
	min-height: 34px;
}
.info-bar .contact-section .date,
.navbar .search-toggle,
.navbar .nav-search,
.post-navigation {
	display: none;
}

And for the warnings. Can you please clarify how you got that warnings? We have checked from our end and there is no any issue.

If you have any problem please let us know.

Thank you!
