. There is no need to edit the code directly and there is no risk of damage to the site. If resources that prevent rendering are run at each load, it may cause great harm to the load time. It is important to defer unimportant JavaScript and CSS that can be loaded later. Use tools such as pagespeed insights to check whether the website has non optimized code, and then manually or the plug-in to correct the problem. Autooptimization and the sister plug-in asyncjs are free options for startup. If there is a problem with the configuration or there is no change, WP rocket is advanced, but provides support and faster settings. W3 total cache is the hardest to use, but it is the best choice if you want to control each file you want to block individually. What is the score of pagespeed before and after optimizing the website? Please leave a message and tell me how big the booth you got!
