Home Page being overridden


I am using the most recent version of Upfront and the Fixer theme.

Currently I am having an issue in which changing the page a button posts to, causes my Home Page to be replaced by the page that the button is on.

Yesterday I created two new pages (Our Team/ Our Board) and then navigated to the 'About' page so I could update the links on the two buttons to point to these pages.

Upon doing so I noticed that my Home (Front) page had been replaced with the About page, with no trace of the home page at all.

Can someone please advise me as to why this may be happening?

I am going to grant support access but I will be restoring my site to a point yesterday as we will need the home page back to it's previous state.

Thanks in advance!
