+Other things you may need to check:
+  - Security plugins may interfere in the image optimization process. Try disabling your security plugin temporarily
+  - Plugins that control page access, like maintenance mode, spam shield, additional authentications page, HTTP/HTTPS alteration, hot-link protection rewrite rule, etc. could also interfere with image optimization. If you have these, try disabling them temporarily.
