Help!! Setting up. Website not working.

Hi there,

I have been trying to set up my site – livingbeautifulinspirations.com for a month, but it is still not working correctly. I also think the site may have been compromised, as today I received a message saying I was in the Matrix, and follow the white rabbit :-/

My issues are:

1. Some of the titles (tags) for the pages are not appearing. (They were earlier today and now I cannot get them back).
2. The difference between categories, menus, pages.
3. My images appear all over the page and do not sit well.
4. My social media buttons do not sit well. Also, where I have a social media site, they are not linking to my social media site.
5. I would like to upload a shopping cart and method for payment.
6. I do not need the comments or blog on each page.

Can anyone help please. Thank you very much.
Kind regards
