upgrading from 3.2.0.5 to 3.2.0.7 breaks the home page.
I can't see the issue because your site has been restored to 3.2.0.5. I suggest you to make dev site. e.g: dev.yoursite.com for test site.
If something happen at upgrade process, we still have time to debugging it first.
FYI: i need FTP access detail for debugging process
