Title: Php 7.4 Last modified: July 28, 2020 --- # Php 7.4 * Resolved [Superb](https://wordpress.org/support/users/themeeverest/) * (@themeeverest) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/) * Hi, I absolutely love your plugin, but ever since I update to php 7.4 autoptimize doesn’t work anymore, it just removes all CSS from my entire website 🙁 * I don’t have the plugin active currently, so I’m not sure if it’s of any help to link my website, but I have done it anyways. * Have you heard of that happening before? * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-7-4-17%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 15 replies - 1 through 15 (of 22 total) 1 [2](https://wordpress.org/support/topic/php-7-4-17/page/2/?output_format=md) [→](https://wordpress.org/support/topic/php-7-4-17/page/2/?output_format=md) * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13180188) * should work perfectly on 7.4 really … do you have a staging-site where we could test? * Thread Starter [Superb](https://wordpress.org/support/users/themeeverest/) * (@themeeverest) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13180202) * [@optimizingmatters](https://wordpress.org/support/users/optimizingmatters/) that was fast, thanks for getting back to me so quickly. I found your beta version link and installed it, it seems like that sorted out the issue – weird! * Marking it as done, thanks for creating an outstanding product * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13180275) * Well, if you were using “inline & defer CSS” then there were issues in 2.7.5 which are fixed in beta (which I’ll release as 2.7.6 today). * Thread Starter [Superb](https://wordpress.org/support/users/themeeverest/) * (@themeeverest) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13180396) * Apparently “Aggregate inline CSS” was the trigger, it mixed the order of some stylesheets which bugged out. * That together with removing the CDN base url did the trick, we are using a CDN enabler instead now and that works. * Not sure I completely understand why the errors suddenly started showing after upgrading PHP to 7.4 though :/ * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13180439) * had a quick look and AO now seems not to be active? * Thread Starter [Superb](https://wordpress.org/support/users/themeeverest/) * (@themeeverest) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13181139) * Hey [@optimizingmatters](https://wordpress.org/support/users/optimizingmatters/) yes it is active, but you’re right it seems like it’s not minifying anything currently, that’s very odd. * In the interface it says: Cached styles and scripts 2 files, totalling 0.00 B( calculated at 14:30 UTC) * I have activated following: – Optimize JavaScript Code? – Aggregate JS-files?– Optimize CSS Code? – Aggregate CSS-files? – Optimize HTML Code? – Save aggregated script/css as static files? – Minify excluded CSS and JS files? – Enable 404 fallbacks? – Also optimize for logged in editors/ administrators? * It seems like minify HTML works fine but the rest doesn’t 🙁 * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13181214) * ok, also configure AO with the CDN base domain, if not AO can’t know it can aggregate the JS/ CSS on that other URL. * Thread Starter [Superb](https://wordpress.org/support/users/themeeverest/) * (@themeeverest) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13181245) * If I type in [https://b9w4c2c6.stackpathcdn.com/](https://b9w4c2c6.stackpathcdn.com/) as the root then all CSS stops working. * It creates a minified file, but it takes a while for stackpath to catch up I think, so for a long while it just leads to a 404 error that looks something like this: * [https://b9w4c2c6.stackpathcdn.com/wp-content/cache/autoptimize/css/autoptimize_6833187de64c366ecc1368911501549c.css](https://b9w4c2c6.stackpathcdn.com/wp-content/cache/autoptimize/css/autoptimize_6833187de64c366ecc1368911501549c.css) * I assume thats the issue, at least it just gives a 404 error * Have you experienced that before?

* in the mean time; try with the “404 fallback”-option ticked maybe? * Thread Starter [Superb](https://wordpress.org/support/users/themeeverest/) * (@themeeverest) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13181342) * I just spoke with Stackpath support, they say that it’s a common error that their service don’t work together with Autoptimize. * They recommend that I use WP Rocket or W3 cache instead. :-/ * Anyways I thank you for your awesome service, I really appreciate it. * Have a great day * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13181392) * that doesn’t make sense … they’re a pull CDN, right? so a file that is created on the origin server and that is requested from the CDN will cause the CDN to pull the file from the origin server? * I see no reason why it would not work and I have seen a great number of sites with AO on stackpath CDN actually .. * If the CDN is disabled, does AO work? * Thread Starter [Superb](https://wordpress.org/support/users/themeeverest/) * (@themeeverest) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13181433) * Well I’ll be honest and say that I have no experience regarding this, so I’m not the right person discuss it with sadly. * I can confirm that AO works fine when the CDN is disabled. * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years ago](https://wordpress.org/support/topic/php-7-4-17/#post-13181463) * Hmm … * So if you have [https://b9w4c2c6.stackpathcdn.com/wp-content/cache/autoptimize/css/autoptimize_6833187de64c366ecc1368911501549c.css](https://b9w4c2c6.stackpathcdn.com/wp-content/cache/autoptimize/css/autoptimize_6833187de64c366ecc1368911501549c.css) not working, does at that moment [https://superbthemes.com/wp-content/cache/autoptimize/css/autoptimize_6833187de64c366ecc1368911501549c.css](https://superbthemes.com/wp-content/cache/autoptimize/css/autoptimize_6833187de64c366ecc1368911501549c.css)( the origin file) work?
