I cannot disable Mod_pagespeed as it is essential to speed up the site as prescribed by Google. Can you give me some additional information on some alternative solution on how to handle this issue? * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years, 7 months ago](https://wordpress.org/support/topic/broken-css-15/#post-12143535) * The problem is both AO and mod_pagespeed try to speed up the site and so optimize CSS (and more) and I have seen mod_pagespeed removing CSS that AO adds. Can’t be 100% sure though, would need to see the site broken for that. If you have a staging site we might break stuff there so we can confirm (or rule out) that this indeed is what’s happening? * Thread Starter [Micheleficara](https://wordpress.org/support/users/micheleficara/) * (@micheleficara) * [6 years, 7 months ago](https://wordpress.org/support/topic/broken-css-15/#post-12144756) * thanks for the answer but unfortunately I don’t have a staging site and even if it were I can’t disable mod_pagespeed to do tests … then I’ll have to take this incompatibility into account and disable the plugin … * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years, 7 months ago](https://wordpress.org/support/topic/broken-css-15/#post-12144790) * too bad, but indeed if mod_pagespeed cannot be disabled (or reconfigured to leave CSS alone) then the only option is to disable AO CCSS. * Thread Starter [Micheleficara](https://wordpress.org/support/users/micheleficara/) * (@micheleficara) * [6 years, 7 months ago](https://wordpress.org/support/topic/broken-css-15/#post-12144817) * thanks for the answer, if there is the possibility to disable only the management of the css then I can ask my developer to disable that function and see how it works! can you confirm that this possibility exists and which parameter must be deactivated exactly? * Plugin Author [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [6 years, 7 months ago](https://wordpress.org/support/topic/broken-css-15/#post-12144851) * Don’t know mod_pagespeed well enough, but Google led me to [https://www.modpagespeed.com/doc/config_filters](https://www.modpagespeed.com/doc/config_filters) and based on the list features in the core set you could try disabling `combine_css, flatten_css_imports, inline_css, rewrite_css`. The exact way how to depends on what webserver you’re using, but is described in the doc 🙂 Viewing 9 replies - 1 through 9 (of 9 total) The topic ‘Broken CSS’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/autoptimize-criticalcss.svg) * [Autoptimize criticalcss.com power-up](https://wordpress.org/plugins/autoptimize-criticalcss/) * [Frequently Asked Questions](https://wordpress.org/plugins/autoptimize-criticalcss/#faq) * [Support Threads](https://wordpress.org/support/plugin/autoptimize-criticalcss/) * [Active Topics](https://wordpress.org/support/plugin/autoptimize-criticalcss/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/autoptimize-criticalcss/unresolved/) * [Reviews](https://wordpress.org/support/plugin/autoptimize-criticalcss/reviews/) ## Tags * [broke](https://wordpress.org/support/topic-tag/broke/) * [css](https://wordpress.org/support/topic-tag/css/) * 9 replies * 2 participants * Last reply from: [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * Last activity: [6 years, 7 months ago](https://wordpress.org/support/topic/broken-css-15/#post-12144851) * Status: not resolved
