After a week and some 4days, I decided to debug this problem once and for all. So I deactivated all Plugins and re-activated them one after the other. To my surprise, an official Plugin from my Hosting was the culprit, “SG-Optimizer” from Siteground was the cause for all my sleepless nights. I’m happy I finally got this solved. I can now sleep well…
My new problem now is, the site’s SpeedTest Score has dropped so significantly, maybe because of code minifications, caching, etc…
Can anyone suggest a good replacement for “SG-Optimizer”?

If you are using Siteground for hosting, try disabling SG-Optimizer in Plugins and see if that solves the problem.

Update 1.7.11.1 leaves site broken, blank screen, does not load page.
Site works fine after uninstall.
How can I fix this?
