Title: Save Changes and Empty Cache? Last modified: August 22, 2016 --- # Save Changes and Empty Cache? * Resolved [wilflare](https://wordpress.org/support/users/wilflare/) * (@wilflare) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/) * thanks for this fantastic plugin, helped alot with resolving my PageSpeed issues. * Just a question – I read on the FAQ the following My cache is getting huge, doesn’t Autoptimize purge the cache? Autoptimize does not have its proper cache purging mechanism, as this could remove optimized CSS/JS which is still referred to in other caches which would break your site. * You can however keep the cache size at an acceptable level by excludinng JS-variables( or sometimes CSS-selectors) that change on a per page (or per pageload) basis. You can read how you can do that in this blogpost. * However, on the settings page there is the option to “Save Changes and Empty Cache” – So has Autoptimize been updated to empty the cache.. or not yet? * [https://wordpress.org/plugins/autoptimize/](https://wordpress.org/plugins/autoptimize/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475322) * If you press “save & empty cache” the cache is effectively emptied entirely, but that’s a one off action triggered by you, not an automatic job running e. g. every week. But pressing “save & empty cache” every month could indeed also help you limit disk usage of AO’s cache. * hope this helps, frank * Thread Starter [wilflare](https://wordpress.org/support/users/wilflare/) * (@wilflare) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475421) * thanks frank! that explains (: * is it recommended to Empty Cache whenever I install or delete plugins as well so Autoptimize can delete the cache and regenerate updated ones? * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475434) * when you install new plugins which add CSS/JS to your blog, autoptimize will automatically pick up on those so new files will be generated. so emptying cache is not needed for that, but it would off course be helpful to keep the cache size as small as possible. * frank * Thread Starter [wilflare](https://wordpress.org/support/users/wilflare/) * (@wilflare) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475504) * thanks Frank! * just one more question – any idea how Autoptimize manages the custom css from Jetpack? I’m about to enable it as a module in Jetpack – not sure if I have to empty my cache etc * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475505) * I try to avoid JetPack (call me old-fashioned), but either the CSS is inlined, in which case AO will automatically create new files in cache, or the CSS is in an external, dynamic file (i.e. .php) and AO will leave it be. So I would enable custom CSS, test and clear AO cache in case of issues. * frank * Thread Starter [wilflare](https://wordpress.org/support/users/wilflare/) * (@wilflare) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475506) * thanks frank (: * yea it has been quite a debate on jetpack but it provides quite a number of useful features for me so I’ll keep it for now. * thank you! * ——– not sure if this is within your scope but I have tried testing my site on gtmetrix and it seems like they are asking me to further minify/compress HTML/ CSS/JS – any thoughts? * [http://gtmetrix.com/reports/www.wilflare.com/1JjXPA8M](http://gtmetrix.com/reports/www.wilflare.com/1JjXPA8M) [http://www.webpagetest.org/result/141113_K7_105K/1/performance_optimization/#compress_images](http://www.webpagetest.org/result/141113_K7_105K/1/performance_optimization/#compress_images) * Thread Starter [wilflare](https://wordpress.org/support/users/wilflare/) * (@wilflare) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475522) * and one more question – is there any setting I must be aware of to make this work with Cloudflare? * Thank you so much frank! * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475530) * Well, only thing I can think of now is to make sure not to have other plugins doing what AO is already doing (i.e. minification). After that it’s enabling Cloudflare (which I’m not a huge fan of either, to be honest) and seeing what the impact is. * Thread Starter [wilflare](https://wordpress.org/support/users/wilflare/) * (@wilflare) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475615) * thanks frank! * just to check for AO, there’s a field for CDN – should I input anything there now that I have Cloudflare enabled? * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475618) * No, the CDN-box only applies to pull CDN’s, which Cloudflare is not. * kind regards, frank Viewing 10 replies - 1 through 10 (of 10 total) The topic ‘Save Changes and Empty Cache?’ 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/) * 10 replies * 2 participants * Last reply from: [Frank Goossens](https://wordpress.org/support/users/futtta/) * Last activity: [11 years, 6 months ago](https://wordpress.org/support/topic/save-changes-and-empty-cache/#post-5475618) * Status: resolved
