Hello, @oceanbulkon,
There is an issue, I don’t know why your service provider doesn’t understand or get it. You can see the image I capture from the links that your service provider shared: https://postimg.cc/D8FZyS60 this is not your site content. It means the site is not loading the content right and stopped loading the page which is why it is showing a good result. But when the site will start loading the content with functionality then it will show the correct score for your site speed. So please share your site wp-admin URL and access in the private content area of this topic by following the below-given format
WORDPRESS ADMIN URL:
WORDPRESS ADMIN USERNAME:
WORDPRESS ADMIN PASSWORD:
So that I will check your issue on your site.
Note: Please take a complete backup of your site first and allow us to debug your site and change/remove the plugins to solve your issues.
Regards 8Themes Team.
