Fix WordPress Critical Health Issue  

WordPress Site Health Status may show you that you have critical issue to fix in order to make your site healthier.
In this quick tutorial, we'll speed up WordPress website by installing a new plugin. WP Super Cache by Automattic is one of the best page cache plugins out there, and solves this issue with few clicks.
The best thing is that you don't need to know how the WordPress cache plugin works, you'll simply need to turn it on. As a result, you've made your site faster and fixed the WordPress critical issue.
It might not work for everyone, and sometimes changing URL structures may have unintended consequences, so make sure everything works afterward. If WordPress Site Health status flares up because the plugin is causing a problem, you can simply turn off / unistall the cache plugin.
I hope it works for you!
