Title: Critical CSS and Beaver Builder Last modified: June 21, 2025 --- # Critical CSS and Beaver Builder * Resolved [Jeffrey Hamilton](https://wordpress.org/support/users/pistoscomputers/) * (@pistoscomputers) * [9 months, 3 weeks ago](https://wordpress.org/support/topic/critical-css-and-beaver-builder/) * Jetpack Boast complains of not being able to build a critical CSS file. The files listed are all templates for buttons produced by Beaver Builder, which I use on my site. I would not consider them critical files. They are perfectly accessible on my end. Yet Boast complains that its regeneration has failed.

Even if those files aren’t truly “critical,” Boost may flag them if it can’t access or analyze them properly. * If the page looks fine and loads normally, you can safely ignore the warning — Boost will simply skip Critical CSS for those templates and continue optimizing other parts of your site. * Let us know if you’d like help reviewing anything further! * Thread Starter [Jeffrey Hamilton](https://wordpress.org/support/users/pistoscomputers/) * (@pistoscomputers) * [9 months, 3 weeks ago](https://wordpress.org/support/topic/critical-css-and-beaver-builder/#post-18522623) * Thanks for the explanation. Is there a way that I can tell Critical CSS to skip certain directories (like Beaver Builder’s templates)? I know it is minor, but having the error flags is annoying and I notice that Critical CSS constantly wants to regenerate the CSS files because it thinks there was an error last time. * Plugin Support [lastsplash (a11n)](https://wordpress.org/support/users/lastsplash/) * (@lastsplash) * [9 months, 3 weeks ago](https://wordpress.org/support/topic/critical-css-and-beaver-builder/#post-18524229) * Hi [@pistoscomputers](https://wordpress.org/support/users/pistoscomputers/) – * Unfortunately, Jetpack Boost doesn’t work based on directories. You’d have to use the stylesheet handles as described here: * [https://jetpack.com/support/jetpack-boost/#concatenate-css](https://jetpack.com/support/jetpack-boost/#concatenate-css) * I’d recommend reaching out to Beaver Builder to ask for a list of handles used by Beaver Builder. * Let us know how it goes. * Plugin Author [Pete (a11n)](https://wordpress.org/support/users/dilirity/) * (@dilirity) * [9 months, 3 weeks ago](https://wordpress.org/support/topic/critical-css-and-beaver-builder/#post-18524371) * Hey there [@pistoscomputers](https://wordpress.org/support/users/pistoscomputers/) * There is a way to “tell” Boost to skip pages from Critical CSS generation. * However, we first need to identify what needs to be skipped. Can you provide your website’s URL so I can take a closer look at what Boost uses? * If you’re not okay sharing it publicly, you can use this form – [https://jetpack.com/contact-support/?rel=support&hpi=1](https://jetpack.com/contact-support/?rel=support&hpi=1) * Just make sure to include a link to this thread. * Once we identify what needs to be skipped, we’ll create a PHP snippet which you can add to your site. * Plugin Author [Pete (a11n)](https://wordpress.org/support/users/dilirity/) * (@dilirity) * [9 months, 2 weeks ago](https://wordpress.org/support/topic/critical-css-and-beaver-builder/#post-18527366) * Hello again. * I’m following up on my last request. I think I managed to find the website and I noticed that templates from Beaver Builder are no longer present on the website. * Critical CSS failed for the `fl-builder-template` post type and hasn’t been regenerated since the 23rd of June. I’ve added a ticket to look into ignoring Beaver Builder related post types from Critical CSS generation. * Currently, the website is broken, and I noticed that WP Fastest Cache is also installed. Both WP Fastest Cache and Jetpack Boost have features that overlap, and sometimes those features aren’t compatible. If you wish to use Critical CSS from Jetpack Boost, I suggest you disable some features related to CSS from WP Fastest Cache, as they seem to be competing with Jetpack Boost for the optimization. * Plugin Support [Stef (a11n)](https://wordpress.org/support/users/erania-pinnera/) * (@erania-pinnera) * [9 months, 1 week ago](https://wordpress.org/support/topic/critical-css-and-beaver-builder/#post-18538878) * Hi there, [@pistoscomputers](https://wordpress.org/support/users/pistoscomputers/), * Do you have updates about that, do you still need help? We usually close inactive threads after one week of no movement, but we want to make sure we’re all set before marking it as solved. Thanks!
