Hello,
Yesterday I purchased "Demeter - one page parallax wordpress theme"
Today I started to build my website, and stumbled upon many problems. 
I have many questions:
1. I need to put a slider at the top of the homepage (http://gc.dugson.com/), but appears the photo with the lamps instead. How can I delete that header? (Same thing happens in every page of the website)
2. I added some Portfolio posts, but cannot find how to insert a filtrable portfolio. Can you explain to me how to do it step by step?
3. In the Contact page (http://gc.dugson.com/contacto/): The layout has 2 columns, in the left one I inserted a Contact form. The second (right column) should show a map, but the map appears down the contact form in the frontend, I don't know why (in the backend builder looks ok)
4. At all the pages, appears to be a right sidebar, but I don´t need it, all pages should be fullwidth. I selected fullwidth layout in the editor, but looks like it is ignoring this.

Can you please help me?
Is there a tutorial, either document, website or videos?

Thanks in advance,
Tamara Cabrera
