Partials messing up massively

I made a website which uses partials. I had to reinstall the MAC OS and put Rapidweaver back on. But the partials have all messed up. I am using Voyager Pro and the Partials are in Extra Content 1 (Banner) and Extra Content 4 (Footer).

But they’ve lost their formatting and on every page they are a mess.

It should look like this http://richpeacock.net/

but it now looks like this

Any help?
