 Since WordPress 4.5 on GoDaddy hosting, the GoDaddy cache seems to break
 the entire WordPress site. The Front page and most external pages show an
 error warning on common browsers like Firefox (also IE), and break the
 Yoast XML sitemap with the same error message when attempting to access
 them.

 Some mitigation occurs by clearing the GoDaddy cache, but the issue comes
 back within a few minutes. Turning off the GoDaddy cache entirely seems to
 have fixed the problem for now. The site used to run without problem
 before WP 4.5 was released.
