I have a website that is live and operational however it is slow. The Page Insight speed is low. https://wpdownloadpro.com/xtra-nulled-full-demo-multipurpose-wordpress-theme/ And since yesterday it has somehow gotten worse and all I did was install then uninstall a plugin. I need to do a clean up I think off old CSS and such. There are details of what I need to change on that speed insight result but the guide on how to fix it there is not good. I tried some of the fixes and it had 0 effect. Is there some code examples or better information I can get from you forum users about how I can speed up my Wordpress based site. It is using Woocommerce and Dokan in a multi-vendor setup.

Incase you are wondering after looking at the name and checking it I made it because I was disgusted by the conduct and privacy policies of Amazon, Facebook, Twitter, Ebay (/Gumtree), Youtube & every single social media/ecommerce platform. It is 100% functional it is just a speed issue which I think can be optimized I just need some expert community advice on how to do this and in a way that does not cause it to be slower. Using some of the plugins for wordpress does absolutely nothing for me and infact 2 made it worse. https://flexi.ink/page-speed-optimization-services
