PHP errors on wordpress

Hi, I'm in a bad place here. I have a site on godaddy, and we decided we'd get better service and a faster site on Bluehost. Well, that has been hellish. I asked them if they'd put it on PHP 7.0, rather than what it was on, PHP 5.6 They said, Oh yes, our servers default to PHP 7.0.

Then they said, Nope we can only get it on 5.6 And I can't have that, because it's being EOL'd shortly. Bluehost is no help at all. So here's where I stand. I changed it to PHP 7.0 single ini.php. And now I have the errors you are seeing here, attached. Bluehost says, they can't help and I need to get a developer. I am hoping someone here can help me out. The files they talk about ARE there.

The nameservers are still at godaddy, so you won't be able to see the Bluehost site unless you change your hosts file as in the attached doc.

I hope someone can help! Thanks in advance!
