Title: GT Metrix show 0 score even though Optimize JavaScript Code was enable?? Last modified: April 24, 2020 --- # GT Metrix show 0 score even though Optimize JavaScript Code was enable?? * Resolved [quyle](https://wordpress.org/support/users/quyle/) * (@quyle) * [6 years, 1 month ago](https://wordpress.org/support/topic/gt-metrix-show-0-score-even-though-optimize-javascript-code-was-enable/) * Hi there, I’ve enable all necessary things in setting area to optimise the CSS/ JS code and have 100% in PageSpeed Score of GT Metrix but in YSLow tab it shows Minify JavaScript and CSS score of 0. I am not sure why it that? Could you please help me explain why? here is screenshot: [http://prntscr.com/s50t30](http://prntscr.com/s50t30) [http://prntscr.com/s50t8o](http://prntscr.com/s50t8o) Also, does your plugin not have clear cache function? as one of the thread you mentioned to a user that he needs to keep WPFC plugin as it provides clear cache button.

You _could_ tick that option, but you’ll have to keep an eye on cache size (which is why it’s off by default). * As for your 2nd question: Autoptimize does have a cache clear function (both in the top menu bar and on the settings page itself), but AO does not do page caching, so I strongly recommend a page caching plugin to be installed (e.g. KeyCDN Cache Enalber or WP Super Cache or WPFC indeed if you have that already). * hope this clarifies, frank * Thread Starter [quyle](https://wordpress.org/support/users/quyle/) * (@quyle) * [6 years, 1 month ago](https://wordpress.org/support/topic/gt-metrix-show-0-score-even-though-optimize-javascript-code-was-enable/#post-12724771) * > That’s the inline javascript when not aggregated quyle. * Thank you for your reply! As shown in the screenshot, I think I have aggregated all of necessary JS files. My cache file is only 4KB when enabling Also aggregate inline JS? option. Is that an acceptable amount? Also, when I test a random blog post, GT MEtrix shows Minify JavaScript and CSS score of 70. Here: [http://prntscr.com/s5612z](http://prntscr.com/s5612z)( but the home page score still 0). Any thought?

I suppose there will be less inline tags? 🙂 * Thread Starter [quyle](https://wordpress.org/support/users/quyle/) * (@quyle) * [6 years, 1 month ago](https://wordpress.org/support/topic/gt-metrix-show-0-score-even-though-optimize-javascript-code-was-enable/#post-12732471) * Hi, Thank you for your reply :d One thing I am not clear about cache size is in the WP dashboard, at the top it shows cache size is 47.25M ([http://prntscr.com/s638op](http://prntscr.com/s638op)), but when I checked it in my Files, it only shows 4KB ([http://prntscr.com/s6391m](http://prntscr.com/s6391m)) Do you know why is that?
