This panel gives you an overview of how many pages NitroPack has optimized.
You also see how long ago a cached page has been purged.
Purge Cache
Clicking this button will delete all cached pages. As a result, cached content won't be served on the next page refresh. Updated content will be seen immediately but with a slight loading delay until NitroPack performs new optimizations.
In most cases, you won't need to use this button. NitroPack automatically invalidates and purges cache, depending on your actions in the WordPress back end.
However, if you changed something on your site and want to show it immediately to visitors, you can use the Purge Cache button.
