Why do I receive “Content Coding Error” when I try to access my website via browser?

Q. Why do I receive “Content Coding Error” when I try to access my website via browser?

This error might occur if you have NextGEN Gallery version 2.0 installed on your website. It has nothing to do with ManageWP plugin and disabling NextGEN Gallery or rolling back to its previous version should resolve the issue.
