MACFEE certificate

Hello!
I need help.
1. I am trying to add the Macfee security seal to my website, the instructions says I should add the Macfee code to my site's HTML, the problem is I am not a developer, I have been working on my store by just following documentations, I have no idea where to find that, I have googled multiple times but i think this is where I now need expert opinion or somebody who just knows.

2. My store is using the journal blog, I am trying to get the blog to have its own page on the home page, like be able to see the 'blog' alongside other categories on the homepage. My store is a clothing store, so the clothing categories are listed on top of the homepage slider/banner, and thats where I want the blog to be as well.
Somebody please help
Thank you.

Since you are using the journal blog, contact the journal extension publisher to integrate your needs.
An alternative solution would be to switch to the default theme of Opencart and see if you are able to add the MCAFee code within the TWIG / TPL home page.
