PHP issue on Cpanel problem

Hello, I have a problem in Cpanel. I have two files in .php that don't seem to be working. My website has been transfered to a new host and since then , the home page does not show and the contact form does not work (these are the two PHP files) I would just like to get this two pages to show correctly ad the contact form to fonction, the domain should be transferred today so I don't have much time
