I have switched on the UCSS option (as well as the CCSS option). As I understand things, this should mean that the combined CSS file should vary depending on the URL tested. However, this same file is being reported (as a source of unused CSS) for all the URLs I have tested. * 2. In addition, there should be no unused CSS at any URL if a unique CSS file is being generated for each URL. * 3. Finally, I have run the Chrome Coverage report on a logged in view of the site (when the cache is bypassed) and this file appears in that report. * Given these observations, I am forced to conclude that this file is not a combined CSS file. If so, how should I deal with it in order to remove its impact on the PSI score? * The latest PSI results for the mobile view can be seen at: * [https://pagespeed.web.dev/analysis/https-dunbarmedical-com/ixfupqjpw7?form_factor=mobile](https://pagespeed.web.dev/analysis/https-dunbarmedical-com/ixfupqjpw7?form_factor=mobile) * Thanks. - This reply was modified 1 year, 3 months ago by [michaeltrotz](https://wordpress.org/support/users/michaeltrotz/). * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [1 year, 3 months ago](https://wordpress.org/support/topic/webpage-loading-unused-scripts-styles/#post-18359314) * when you have UCSS generated , you will see file as `/wp-content/litespeed/ucss/ xxxxx.css` , or embed into inline style with name `litespeed-ucss` * and if you check the html source comment at bottom * ```wp-block-code ``` * the UCSS generation is still in queue * Thread Starter [michaeltrotz](https://wordpress.org/support/users/michaeltrotz/) * (@michaeltrotz) * [1 year, 3 months ago](https://wordpress.org/support/topic/webpage-loading-unused-scripts-styles/#post-18360436) * Thanks for the feedback. Is there a way to force prioritization of certain URLs where generation of UCSS and CCSS is concerned? Otherwise, how long will it be before I can see the effect of UCSS/CCSS for the home page URL? * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [1 year, 3 months ago](https://wordpress.org/support/topic/webpage-loading-unused-scripts-styles/#post-18361496) * unfortunately no , but you can clean the ucss queue , then access the ones you want to generate first manually , then this way they should be put into first queue * the time it takes for generation would vary , depends on your quota , generator node load …etc * Thread Starter [michaeltrotz](https://wordpress.org/support/users/michaeltrotz/) * (@michaeltrotz) * [1 year, 3 months ago](https://wordpress.org/support/topic/webpage-loading-unused-scripts-styles/#post-18361835) * OK – thanks. PSI is also reporting that there are several images (like the logo) that should be served in next gen formats like WebP. It is also suggesting the used of the Performance Labs plugin to achieve this. I have that plugin installed already but am not using it for that purpose in case it conflicts with LiteSpeed. Is there a way to use LiteSpeed to deal with that issue, or should I use another plugin like Performance Labs for that? * Thread Starter [michaeltrotz](https://wordpress.org/support/users/michaeltrotz/) * (@michaeltrotz) * [1 year, 3 months ago](https://wordpress.org/support/topic/webpage-loading-unused-scripts-styles/#post-18361958) * The logo file reported by PSI as needing conversion to WebP (or other next gen format) is [https://dunbarmedical.com/wp-content/uploads/2023/09/Logo.jpg](https://dunbarmedical.com/wp-content/uploads/2023/09/Logo.jpg) * Is there a way to check whether a WebP version of this file has already been generated by LiteSpeed and, if so, why is it not being used to generate website pages (according to PSI)? * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [1 year, 3 months ago](https://wordpress.org/support/topic/webpage-loading-unused-scripts-styles/#post-18365717) * you can go to Media , in the right-side column , it should have an indicator to indicates the optimization for images * some images may not get webp version for various version , or it has not been optimized yet * Thread Starter [michaeltrotz](https://wordpress.org/support/users/michaeltrotz/) * (@michaeltrotz) * [1 year, 3 months ago](https://wordpress.org/support/topic/webpage-loading-unused-scripts-styles/#post-18366937) * Hello – Going back to the UCSS issue, only 2 of these files have been generated and I have found the following message in the third css file: * /* [ERROR] UCSS generation took too long. Likely your CSS and/or HTML will need to be optimized. Please correct this and try again. */ * Can someone suggest how to get around this issue and continue generating used CSS files? * Thanks. * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [1 year, 3 months ago](https://wordpress.org/support/topic/webpage-loading-unused-scripts-styles/page/2/#post-18370197) * unfortunately I don’t have good solution to this * there is a limit cap on size and time for UCSS / CCSS generation * by the error message you posted , please try to shrink a bit the page to make it below the limit * also we are testing something about UCSS internally , which also comes with wider limit range that could potentially work for you without you to do anything.
