Title: CSS lost on some pages Last modified: January 8, 2021 --- # CSS lost on some pages * Resolved [iTeamWP](https://wordpress.org/support/users/iteamwp/) * (@iteamwp) * [5 years, 7 months ago](https://wordpress.org/support/topic/css-lost-on-some-pages/) * Hello, * LiteSpeed Report ID: IGDVAAMZ * We’ve noticed an issue on a few of our clients sites recently which all use the LiteSpeed page optimisations. * Sometimes when viewing a page the CSS does not appear for that page, meaning the page basically loads as plain text. * This always seems to target a specific page e.g. it doesn’t effect the whole site and usually the issue resolves itself when the LiteSpeed CSS is rebuilt. * We’ve only noticed this error since updating to the latest version of LiteSpeed. * Any advice please? We don’t want to disable LiteSpeed optimisations as they help with our Google PageSpeed score. * Thanks.

If an error occurs with the LiteSpeed CSS merging would the file potentially not be included in the header of the page? * Thanks. * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [5 years, 7 months ago](https://wordpress.org/support/topic/css-lost-on-some-pages/#post-13905125) * Hi, * > Any ideas if this is feasible?

Are you suggesting disabling HTTP/2 Push might be a good idea? * Thanks. * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [5 years, 6 months ago](https://wordpress.org/support/topic/css-lost-on-some-pages/#post-13956396) * Hi, * No , upon our last conversation: * you thought maybe CSS was not included into HTML source , in which I suggest to , check the HTTP header , because as you have enabled push , these files will be shown up in response header as `link` header to push resources. * so this way , you can compare the HTML source code and HTTP response header to see if the CSS files are same on both sides. * Best regards, * Thread Starter [iTeamWP](https://wordpress.org/support/users/iteamwp/) * (@iteamwp) * [5 years, 1 month ago](https://wordpress.org/support/topic/css-lost-on-some-pages/#post-14608100) * Hi [@qtwrk](https://wordpress.org/support/users/qtwrk/) , * This issue has become a lot more common recently on our clients websites. * We’ve noticed that when the issue occurs the CSS is included in the CSS HTML source so that’s not the cause of the issue. * What is the cause is the CSS that is being generated by LiteSpeed. * E.g. Recently the “About Us” page on our website suffered this issue. * During this time the following file wp-content/litespeed/cssjs/ded8b.css?37e3d was only 25.8kB missing the majority if not all of our styles. * After flushing the LiteSpeed cache the page returned to normal and the stylesheet changed to /wp-content/litespeed/cssjs/8b0ee.css?af9cf with a size of 177kB. * So LiteSpeed had generated a CSS file for the page with ~150kB of styles missing from the stylesheet. * As mentioned previously this issue has become increasingly common so would appreciate any advice as when this issue occurs it’s basically makes the site completely unusable for any visitors until we flush the cache. * Thanks. * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [5 years, 1 month ago](https://wordpress.org/support/topic/css-lost-on-some-pages/#post-14608130) * Hi, * please create a ticket by mail to `support at litespeedtech.com` * my colleague will follow you up * Best regards, Viewing 12 replies - 1 through 12 (of 12 total) The topic ‘CSS lost on some pages’ is closed to new replies. * ![](https://ps.w.org/litespeed-cache/assets/icon-256x256.png?rev=2554181) * [LiteSpeed Cache](https://wordpress.org/plugins/litespeed-cache/) * [Frequently Asked Questions](https://wordpress.org/plugins/litespeed-cache/#faq) * [Support Threads](https://wordpress.org/support/plugin/litespeed-cache/) * [Active Topics](https://wordpress.org/support/plugin/litespeed-cache/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/litespeed-cache/unresolved/) * [Reviews](https://wordpress.org/support/plugin/litespeed-cache/reviews/) * 12 replies * 2 participants * Last reply from: [qtwrk](https://wordpress.org/support/users/qtwrk/) * Last activity: [5 years, 1 month ago](https://wordpress.org/support/topic/css-lost-on-some-pages/#post-14608130) * Status: resolved
