Hello again!

It seems like your site is still only generating one critical CSS file and timing out for the rest. This is likely a firewall or hosting limitation.

The critical CSS generator needs to load several pages of your site. This may be triggering a page load limit set by a firewall, or exhausting the resources available from your host.

From here I would recommend two things.

1. Try disabling other plugins for testing purposes and see if you can generate critical CSS and the health check goes away. If this is successful, a plugin is limiting the requests. Try to find out which plugin is causing it.
2. Contact your hosting provider and explain this issue. Mention that you need to load several pages subsequently without cache.

Hi @sarita23, We have recently shipped Jetpack Boost 2.0.2 with a fix for critical CSS generation issues. I noticed that your site is currently serving critical CSS, so I assume the update worked for you and marking this thread as resolved. However, if you still face this issue, please reply with the errors you see when critical CSS generation fails.

Hey @ildomandatore, you can use Concatenate CSS and Concatenate JS features in Jetpack Boost to minify the files.

Unfortunately, Jetpack Boost cannot help optimize ads at the moment.

I hope this helps.

Hey @kramerpm! It looks like the server sometimes throw a 500 error causing the critical CSS generation to fail. Please contact your host to find out what may be causing them.

If you would like to reply, please open a separate thread so we can focus on your issue.

Hi @slugman666! The plugin has no mechanism to turn on modules automatically after you turn them off. So, it would be either another administrator turning on the feature or another plugin altering Jetpack Boost’s settings.

If you see that the modules turn back on instantly, it can indicate that the Jetpack Boost settings page has expired. Retrying after refreshing the page should fix the issue.

Hi @kuechenlatein! I am sorry to learn that you are still facing this issue. From your screenshot, only one critical CSS file was generated. Ideally, there will always be more than one.

After looking at the stats, it appears that the critical CSS generator timed out while trying to load some pages of your site. The critical CSS generation happens in your browser, so it is essential that the browser tab is open and there is a stable internet connection while generating critical CSS. If it is still failing while you are trying on a stable connection, please reach out to your host and they might be able to help you.

Hi again!

I am glad that it worked out for you. Thank you so much for letting us know. We have released Jetpack Boost 2.0.2 to address this issue permanently.

Hi @fertombino !

We have released Jetpack Boost 2.0.2 today which addresses compatibility fix with Yoast and All in One SEO that would impact critical CSS. Can you please update the plugin, try again, and let us know?

Hey @processus16!

Thank you for opening a separate thread!

It looks like you are using the Yoast SEO plugin. The “Crawl Optimization” feature in Yoast can create the redirects that are causing the critical CSS to fail. We are currently working on a permanent solution to this.

Meanwhile, to workaround this in your site, you can whitelist boost’s url parameter in Crawl Optimization. To do this you have to go to:
WP Admin > Yoast SEO > Settings > Advanced > Crawl Optimization and add jb-generate-critical-css under Additional URL parameters to allow.

Please not that the redirects may be cached by your browser and it may continue to fail even after you change this setting. To overcome this, please clear the browser cache or try from a fresh Browser.

See the screenshot for example:

Hi @180turnaroundmarketing

It seems like you are using the All in One SEO plugin, and there is a conflict that we will release a fix for soon. For now, you can work around this issue by going to All in One SEO settings and adding jb-generate-critical-css under allowed query args for Crawl Cleanup. See the screenshot for clarity.

Please note that browser cache may still interfere even after you make the change. So, make sure to cleanup your browser cache or use a fresh browser to generate critical CSS.

Hello @processus16!

To avoid confusion and mix-ups, could you kindly open a new thread detailing your issue? It’ll help us assist you more effectively.

I have looked into your website though and I do have some insights. So, please mention me in the issue so that I get notified.

Hi @fertombino!

When I visited your site, the stylesheets did not appear to load. As a result boost could not find any stylesheets to work with. Please see if any of your other plugins are preventing your stylesheets to load.
