Title: CDN not working Last modified: August 20, 2016 --- # CDN not working * [raphaelsuzuki](https://wordpress.org/support/users/raphaa00/) * (@raphaa00) * [13 years, 1 month ago](https://wordpress.org/support/topic/cdn-not-working/) * Hi. * The CDN rewrite feature seems to be not working. * Is it Apache based? * I’m asking because I’m using Nginx. * [http://wordpress.org/extend/plugins/autoptimize/](http://wordpress.org/extend/plugins/autoptimize/) Viewing 15 replies - 1 through 15 (of 23 total) 1 [2](https://wordpress.org/support/topic/cdn-not-working/page/2/?output_format=md) [→](https://wordpress.org/support/topic/cdn-not-working/page/2/?output_format=md) * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [13 years, 1 month ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604084) * Don’t think the rewrite is Apache-specific, but done entirely in PHP. But I’m not familiar with the CDN-rewrite code yet to be honest (I took over maintenance from the original developer a couple of months ago), I’ll dive in to see how it works. * Some questions; - Did you activate JS, CSS or image CDN? - Do you use any kind of caching (e.g. WP Super Cache plugin) and if so did you clean the cache? - Did you just see your normal URL’s in the resulting HTML after activating the CDN-config? Or were the URL’s broken? Or were some OK and others not? * Thread Starter [raphaelsuzuki](https://wordpress.org/support/users/raphaa00/) * (@raphaa00) * [13 years, 1 month ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604129) * Hi, Futta, and thanks for the fast response. * > Did you activate JS, CSS or image CDN? * I’ve done tests with them all enabled and with each individually enabled. None of them seems to work. * > Do you use any kind of caching (e.g. WP Super Cache plugin) and if so did you > clean the cache? * I don’t use any type of WP-specific cache, but I do use APC on my server, with“ apc.stat” directive set as “1”. * > Did you just see your normal URL’s in the resulting HTML after activating the > CDN-config? Or were the URL’s broken? Or were some OK and others not? * Nothing’s changed, actually. * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [13 years, 1 month ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604139) * OK, did [a quick test on my test-blog](http://futtta.be/wordpress/blog/2012/09/07/need-more-random-posts/) and Autoptimize’s CDN code seems to work for me, so it’s probably something specific to your configuration. Can you list of all of Autoptimize’s settings here (or in a mail to futtta-at-gmail-dot-com)? * Thread Starter [raphaelsuzuki](https://wordpress.org/support/users/raphaa00/) * (@raphaa00) * [13 years, 1 month ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604143) * My configuration is as follow: * – HTML and CSS minify; – All CDN options: js.mysite.com, css.mysite.com, media. mysite.com; – Disabled file compress (doing it with Nginx). * I’ve made this tests with two different sites. In one of them I disabled all other plugins, without success. * Maybe this is something to do with my server? * – PHP 5.4.6 + APC – MariaDB 5.5.29 – Nginx 1.2.1 + PHP-FPM * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [13 years, 1 month ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604178) * The server-stack should not have anything to do with the problem, as the replacement of URL’s with CDN URL’s is done with pretty straightforward PHP preg_replace’s. * But I’m working on some issues with the latest release for now, but as soon as that calms down I’ll look into this problem again. * I must admit that I consider CDN as being less part of the core functionality of (or less vital to) Autoptimize. I use the CDN-options in WP Super Cache (which is the ideal companion to Autoptimize) to offload CSS/JS/images to my CDN. * [John Conner](https://wordpress.org/support/users/johnconner/) * (@johnconner) * [13 years ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604208) * Hi futta, the CDN option is somehow weird, it seems working at the very first moment of installation, after a clean catche it stops working at all 🙁 * Thread Starter [raphaelsuzuki](https://wordpress.org/support/users/raphaa00/) * (@raphaa00) * [13 years ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604209) * > I must admit that I consider CDN as being less part of the core functionality > of (or less vital to) Autoptimize.

The thing is **there should be a PHP way** to keep its CDN **always working**, I found out that it could be stopped with other WP settings or plugins. Any help is appreciated 🙂 * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [13 years ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604211) * > I found out that it could be stopped with other WP settings or plugins. * That is interesting, can you provide some more info on that? * [John Conner](https://wordpress.org/support/users/johnconner/) * (@johnconner) * [13 years ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604212) * > can you provide some more info on that? * I can’t surely claim that these situations would happen generally: 1- updating wp from 3.3 to 3.5.1 or bp from 1.6 to 1.7 2- installing wp better security intrusion module 3- changing permission of autoptimize folders from 755 to any (e.g.705) 4- activating “deflate” with .htaccess every one of these cases happened on a different site, they’re assumed as independent variables (no other changes), and again I can’t admit these are just conflicting with autoptimize CDN. I like the plugin, so I continue installing on my wp sites even if CDN goes out of work. * [John Conner](https://wordpress.org/support/users/johnconner/) * (@johnconner) * [13 years ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604213) * Just found out with reseting the plugin installation in sql tables, the CDN works again, both js $ css; tnx everyone 🙂 * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [13 years ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604214) * Hurray! * But for my understanding; “resetting the plugin installation” = removing autoptimize options to go back to default? * [blau](https://wordpress.org/support/users/blau/) * (@blau) * [13 years ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604216) * Slightly offtopic: I use Autoptimize together with WP Super cache and what I like is the ability to offload css+js to a CDN with Autoptimize. I may also add, it works failry well for me. * [cp_user](https://wordpress.org/support/users/cp_user/) * (@cp_user) * [12 years, 12 months ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604229) * Hi, * Would you care to elaborate more on the: * Just found out with reseting the plugin installation in sql tables, the CDN works again, both js $ css; tnx everyone 🙂 * Do you mean re-installing or what? * Tnx * [cp_user](https://wordpress.org/support/users/cp_user/) * (@cp_user) * [12 years, 12 months ago](https://wordpress.org/support/topic/cdn-not-working/#post-3604230) * The Autoptimize works perfect without using CDN. As soon as CDN is used, Autoptimize stops working. Thats to bad as CDN is vital for some websites. * I use the CDN Linker from GitHub.com to connect with my account with SoftLayer. So far the only plugin that works with CDN is the JS & CSS Script Optimizer Plugin( The JS works – but not the CSS). * So it seams to be hard to find a plugin that optimizes both JS & CSS and have it both working with CDN. * Hopefully Autoptimize can solve this and make it a highly desired plugin. * Cheers RK Viewing 15 replies - 1 through 15 (of 23 total) 1 [2](https://wordpress.org/support/topic/cdn-not-working/page/2/?output_format=md) [→](https://wordpress.org/support/topic/cdn-not-working/page/2/?output_format=md) The topic ‘CDN not working’ is closed to new replies. * ![](https://ps.w.org/autoptimize/assets/icon-256X256.png?rev=2211608) * [Autoptimize](https://wordpress.org/plugins/autoptimize/) * [Frequently Asked Questions](https://wordpress.org/plugins/autoptimize/#faq) * [Support Threads](https://wordpress.org/support/plugin/autoptimize/) * [Active Topics](https://wordpress.org/support/plugin/autoptimize/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/autoptimize/unresolved/) * [Reviews](https://wordpress.org/support/plugin/autoptimize/reviews/) ## Tags * [cdn](https://wordpress.org/support/topic-tag/cdn/) * 23 replies * 5 participants * Last reply from: [Frank Goossens](https://wordpress.org/support/users/futtta/) * Last activity: [12 years, 11 months ago](https://wordpress.org/support/topic/cdn-not-working/page/2/#post-3604240) * Status: not resolved
