Title: Uncompressed, Uncached JavaScript & CSS Last modified: November 23, 2022 --- # Uncompressed, Uncached JavaScript & CSS * [driver49](https://wordpress.org/support/users/driver49/) * (@driver49) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/) * I am bringing this site back from the dead, and trying to make it as accessible and crawl able as possible. * Semrush tells me my WP installation has “2,899 issues uncompressed JavaScript and CSS files.” Also (I suspect not coincidentally) I have “2,899 issues with uncached JavaScript and CSS files.” * Can this be addressed with the right plugin? * I have a couple of plugins already that address ‘JavaScript’: * Async JavaScript Autoptimize Flying Scripts * …as prescribed by a tutor I am following…. but while the plugins are activated, it’s not clear that they are ‘enabled’ or configured properly … * … or if either of them offers the solution to this compression issue. * Where do I even start? * –PS * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Funcompressed-uncached-javascript-css%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 15 replies - 1 through 15 (of 20 total) 1 [2](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/page/2/?output_format=md) [→](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/page/2/?output_format=md) * [ahmadalim](https://wordpress.org/support/users/ahmadalim/) * (@ahmadalim) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/#post-16226507) * Hi there, * I believe the issue can be solved by utilizing the plugins that you have already used. As one of the plugins that you are using is Autoptimize, I recommend asking at [Autoptimize Forum](https://wordpress.org/support/plugin/autoptimize/) so the plugin’s/theme’s developers and support community can help you with this. * You can also check [this article](http://The Ideal Autoptimize Settings 2022 To Optimize CSS, JavaScript, Misc Settings) to help you get the optimal setting for the plugin * Hope this helps. - This reply was modified 3 years, 6 months ago by [ahmadalim](https://wordpress.org/support/users/ahmadalim/). - This reply was modified 3 years, 6 months ago by [ahmadalim](https://wordpress.org/support/users/ahmadalim/). * [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/#post-16226515) * Hey, the Autoptimize developer is here already 😉 * When checking the HTML source code I don’t see any reference to AO being active.

I have not clicked either “Save Changes” or “Save Changes and Empty Cache” at the bottom of the page. * I’m in no hurry, I’ll wait till I see a response here before I pull that trigger. * You might also advise re: the [Images] [CriticalCSS] [Extra] and [Optimize More!] tabs. * Also please check this URL (above) You can also check this article to help you get the optimal setting for the plugin — the page linked above didn’t open for me. * Thanks, * –PS * [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/#post-16228055) * I would simply activate “optimize JS”, “optimize CSS” and “optimize HTML” and click on “save changes” for starters and re-test.

You can use a plugin for example: --- https://blog.litespeedtech.com/2018/03/21/using-the-lscache-plugin-without-litespeed-server/ --- We also offer LiteSpeed Web Server licenses, which provides best-in-class caching via LSCache and a host of other features including various forms of page compression. --- https://blog.litespeedtech.com/2021/03/29/litespeed-web-server-v6-0/ --- CloudFlare is a service that sits in between the public internet and your website. They essentially "intercept" traffic to your site (with your consent, of course) and serve visitors a cached copy of the site from their own servers whenever possible. This reduces load on your server and can improve delivery to visitors. Since it receives content before giving it to your visitors, it also has the ability to minify CSS and JavaScript, compress pages, and so on. Your server is currently configured using PHP-FPM and Apache's Worker MPM. We can switch you over to the Event MPM for added performance. http2 can also be installed. ``` * – – – – – – * Care to weigh in on any of that? * Thanks, * –PS * [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/#post-16228296) * Don’t know litespeed well enough, but as for Apache; ask your host if mod_deflate and/ or mod_zip are installed (needed for compression) and mod_expires (for cacheability). if that is the case [some simple additions](https://gist.github.com/lukecav/c806c253608a7b9abfcb572bf46eb54c) to the .htaccess file in the wordpress root directory suffice to get rid of those semrush warning. * if not you can disable the “serve as static files” option in Autoptimize’s main tab and then the number of warnings should go further down. * Thread Starter [driver49](https://wordpress.org/support/users/driver49/) * (@driver49) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/#post-16229208) * I’m a little lost now on what has been done and what else needs to be done. * My Host informed me that there is “no cost associated with the PHP-FPM+mpm_event or http2 changes.” So I asked him to go ahead and implement those. * A while later I was advised: * ``` ===== Configuration After PHP-FPM Changes ===== Domains using each version of PHP: --- 3 ea-php74 11 ea-php81 === Domains using PHP-FPM: 14 === Current PHP handler configuration: --- DEFAULT PHP: ea-php74 ea-php74 SAPI: cgi ea-php80 SAPI: cgi ea-php81 SAPI: cgi === Current Apache Configuration: --- mpm_event_module (shared) http2_module (shared) === Sites running open_basedir: 14 ``` * – – – – * …but sadly I have no idea what a word of that means. * I would like to continue configuring Autoptimize, though. Remember the link you sent in your first reply to me here was broken, so if there’s stuff I can figure out from that please resend the link. * I think LiteSpeed (whatever it is) is out of the question because that was going to be $36/mo. * Are you familiar with Cloudflare? That’s the next thing I am going to look into. * I have over 100 things – out of date posts, mostly – that I need to fix before I run another Audit w Semrush … maybe over the weekend. * Thanks again, and Happy Special Thursday in November Day. * –P * [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/#post-16229698) * the “Configuration After PHP-FPM Changes” is just a description of the current configuration, it is not actionable by you. * in Autoptimize’s main configuration screen (“JS, CSS & HTML”), near the bottom untick the “serve as static files” option. * Thread Starter [driver49](https://wordpress.org/support/users/driver49/) * (@driver49) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/#post-16231989) * I wonder who is working today…? * I don’t see a “serve as static files” option. * I do see * ‘Save aggregated script/css as static files?’ * …and since that is the only use of the word ‘static’ under that tab, I unchecked that one. * There will be more, perhaps over the weekend or early next week. * Thanks, * –PS * Thread Starter [driver49](https://wordpress.org/support/users/driver49/) * (@driver49) * [3 years, 6 months ago](https://wordpress.org/support/topic/uncompressed-uncached-javascript-css/#post-16232015) * After I changed that setting, the top of my Plugins panel says * ‘It looks like your site might not have page caching which is a must-have for performance.
