How do i reset my homepage to the way it looks on the premiumpress website

Hi. I’m very new to premiumpress as i recently left Templatic, so please bear with me. I’ve adjusted a setting when i first installed and was playing around with the site, now it’s stuck on the login page when you first visit the url. My intention was to keep the photo background layout, but replace the I’m looking for search area, with user registration instead.

Any help will be appreciated. Thanks
