My settings already match what you have shown above.
I’ve attached the console log. This is the only thing in the console log before and after.
The one thing I did find that, at least for me, using Chrome in incognito mode never gets past the broken render view of the page even after refreshing, forcing to clear the cache, or visiting the page in another browser. If I view it first while in incognito mode I can’t get the correct result. Same sort of behavior I’ve seen in Safari. Still though if I view the page first in normal Chrome and refresh the page it looks fine in those browsers.
It does seem like I am unable to totally disable caching on my hosting provider WP Engine. And if I clear the cache on the server side it fixes the issue for just the page that has been viewed. Same can be done by adding a cache buster to the URL like “?foo=bar”
Still though if I deactivate the Ajax Search Pro plugin this issue goes away.
