Can't get back to a revision

Something happened and I lost a lot of my customization on the home page. I need to go back to a revision but when I click on one I get a blank screen. The page is not reverted back either.

Hello there,

I am sorry to hear that you’ve run into trouble. I’d like to help, but I am quite unclear. Did you mean page revisions?

What will happen if you temporarily disable all plugins except Page Builder first, then re-run revisions roll-back?

Regards,
Kharis

Yes, page revisions.

I tried your suggestion but I still get a blank screen. My biggest
problem is the big white box that says Homepage here:
http://www.locatefreequotes.net/. I think I can fix the other things.
But I’d still like to be able to get to the revisions.
