New Problem

Yesterday I tried to change my page background. That still isn’t working, btw. (another thread) Today I changed the images in my meta slider. I clicked Save & Preview and they showed up normally. But when I visit my website, the page is empty. I’ve cleared the cache (again) and the page still empty.

A week ago, the day before I tried to change the page background, I got the email that informed me of the upgrade to 4.7.3. So far I’m not a fan.

How do I fix this???
