This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.
If that doesn’t help…
Can you post a screen shot of what you see before it snaps at you?

So I changed the theme to 20-12 and deactivated all the plug ins. Then I checked out the homepage. It told me that I had a missing widget. The one in question is Black Studio Tiny MCE. I re-installed it, and the page won’t load. I don’t know if that narrowed down the problem or not.
Black Studio Tiny MCE is fine. But I think we have a winner, or is that loser? Page Builder by Site Origin. I’ve got everything else up and the homepage editor is working just fine. I install Page Builder, and it won’t load. Vantage theme works fine too.
So my next question is: I rather liked working with Page Builder, when it was working. Can you suggest a viable alternative?
I’m not a fan of page builders. There are lots if you look in the plugin directory.
