Opencart Pro for site speed, updates and optimization on https://buysunmedcbdoil.com

I need this site to be optimized for functions and speed on GT Metrix and loading, caches cleaned and images being able to be seen on new products I load on updates, need updates on site. When orders come in I am not getting emails anymore I only get it thru the app installed I was thinking maybe because of heavy cache or something which I know has to be minified. But if you go thru it and the pages you will see and also check GTMetrix which is now scoring a D. I would love to see an A because it is my best SEO-optimized site but it has been lacking for about a week so I feel it needs to be updated and cleaned to the best of a pros knowledge and GTMetrix and all errors removed that can be found, so I am looking to hire someone for that. I need it to work great. The other important thing is communication and the job done ASAP not prolonging for an extended amount of times. Leroy https://buysunmedcbdoil.com
