-After LiteSpeed cache for Prestashop enabled, the user see very fast loading speed as 464 ms for TTFB through the browser. Also Gtmetrix and Pingdom work well. However [[https://developers.google.com/speed/pagespeed/insights/|google PageSpeed Insights]] constantly shows ''0'' result.
-Google states: ''Lighthouse returns a Performance score between 0 and 100. 0 is the lowest possible score. A 0 score usually indicates an error in Lighthouse. If you see a 0 score repeatedly, please file a bug on the Lighthouse repo.'' from [[https://developers.google.com/web/tools/lighthouse/v3/scoring|here]].
-It looks like something wrong there.
-Please beware that Prestashop has internal smarty cache, which may lead to poor pagespeed insights sore, is nothing to do with LiteSpeed Cache for PrestaShop. Clear Prestashop internal cache then everything fine.
-Steps: PrestaShop Admin-> Advanced Parameters -> Performance -> Clear cache.
