I am trying

I am trying to reduce my website load time. However, when I conduct a test using GTmetrix the website takes approximately 9 seconds and displays the attached errors.

I am trying to rectify the Defer parsing of JavaScript and Leverage browser caching using Hummingbird. Although I tried to rectify it using Hummingbird it is not reducing the load time or fixing the error. Can you help me.

Kind regards,
