I’ve taken a look at your site and noticed that Critical CSS was successfully regenerated last time on Thursday, 15 February 2024 10:32 GMT. Can you please confirm if it works for you now? If the issue persists, please let me know if there’s any specific error mentioned in Jetpack Boost for you when Critical CSS fails to regenerate. * Thread Starter [omsuraj](https://wordpress.org/support/users/omsuraj/) * (@omsuraj) * [2 years, 3 months ago](https://wordpress.org/support/topic/jetpack-critical-css-not-generating/#post-17430504) * Yes it was generated but why boost got reduced to down * Plugin Support [Alin (a11n)](https://wordpress.org/support/users/alinclamba/) * (@alinclamba) * [2 years, 3 months ago](https://wordpress.org/support/topic/jetpack-critical-css-not-generating/#post-17430667) * Hi [@omsuraj](https://wordpress.org/support/users/omsuraj/), * > Yes it was generated but why boost got reduced to down * It’s great to hear that Jetpack Boost has regenerated Critical CSS for your site. However, I’m a bit unclear on what you meant by “got reduced to down.” If you’re aiming to improve your site’s speed scores using Boost, I encourage you to explore [our support page](https://jetpack.com/support/jetpack-boost/improving-your-site-speed-score/), which offers comprehensive insights on enhancing site speed. * [shammah2023](https://wordpress.org/support/users/shammah2023/) * (@shammah2023) * [2 years, 3 months ago](https://wordpress.org/support/topic/jetpack-critical-css-not-generating/#post-17431365) * I’ve been having the same issues with my site for the past week, trying to get the critical CSS to generate. Well, low and behold, if it didn’t just generate. So obviously it is not my site but something to do with the program itself given the number of people having issues. * Also wanted to comment that I noted it says to do this whenever we make changes to the html or css structure of our sites. I haven’t taken any of those steps/ actions, so can’t see why it would have been necessary in the first place. * All is well – for now. * Plugin Support [Alin (a11n)](https://wordpress.org/support/users/alinclamba/) * (@alinclamba) * [2 years, 3 months ago](https://wordpress.org/support/topic/jetpack-critical-css-not-generating/#post-17439216) * Hi [@shammah2023](https://wordpress.org/support/users/shammah2023/), * Regarding Critical CSS generated unexpectedly without making any changes to the site, it’s possible that changes in content or updates by themes or plugins could trigger a need for regeneration of Critical CSS. However, if all is working well now, that’s great to hear. * Remember, maintaining and optimizing site speed is an ongoing process, and it’s recommended to regularly check and optimize various aspects of your site. * Given the issue initially discussed here is fixed, I’m going to mark this thread as Resolved for now. * Thank you!
