Troubleshooting WP SuperCache Bugs
What is WordPress SuperCache plugin?
Speed is a highly important factor in ranking pages for SEO and being able to provide your users with a page quickly will enhance your ranking over competitors that are delivering their pages slower. One method to improve the speed of delivery is to provide your users with a cached version of your page. A page is generated by the site running php to create an HTML version of your page which is displayed by the browser. What a cache does is to keep that HTML version available so that it can quickly deliver it to any visitor rather than generating the page from scratch every time. There are several plugins that you can use to do this but one of the most popular with well over a million users is the WP Super Cache.

Homepage is not being cached
Another issue that many Supercache users report is that although all of the other pages on the site are being cached and served correctly that the homepage itself is not being cached correctly especially if very long periods are selected for the cache.
