Unable to save, ERR_EMPTY_RESPONSE, This page isn’t working didn’t send any data

So for several days now, I have been having intermittent problems saving/updating posts when using Google Chrome. I think this started over the weekend of 9/23/17. I get this error:

This page isn’t working
naturallyliz.com didn’t send any data.
ERR_EMPTY_RESPONSE

I have tried deactivating all plugins, resetting plugins and major settings to factory. I have deleted all cookies, browser, cache, etc in Chrome, on my computer. Everywhere I know or can think of.
Even uninstalled Chrome, ran scans on computer, rebooted, cleared cache, etc then reinstalled.
When I hit save, sometimes it works fine, other times it hangs up then goes to error. When I go back in, sometimes it will say it saved a version in my browser. I can restore and SOMETIMES I can immediately hit save and it will do so, other times it will not.
I have switched over to Firefox. Not having the problem as often but it has happened a couple times now.
Currently the only plugin running is Wordfence. I have deactivated and deleted. Still had the problem and reinstalled/activated.
Please assist. I am getting so frustrated. Haven’t been able to work for over a week!
