Failed to generate Critical CSS

Hi there,

Thank you for reaching out about the issue with generating Critical CSS for your site. The error message you’re encountering typically suggests that there may have been a temporary issue, and retrying often resolves the problem. However, if the issue persists, there are a few steps you can take to troubleshoot it further.

1. Check for Plugin Conflicts: Sometimes other plugins can interfere with the generation of Critical CSS. Try disabling other plugins temporarily to see if that resolves the issue.
2. Server Resources: Ensure your server has enough resources to process the Critical CSS generation. This process can be resource-intensive, and limited server resources can cause it to fail.
3. Check for Console Errors: Use the browser’s developer tools to check for any console errors that might indicate what is going wrong.
4. Review Server Logs: Your server error logs may provide additional insight into what is causing the failure.

If none of these steps help, then please, reply in this thread with any additional details or error messages you might be seeing. Also, if you’ve noticed any patterns on when the error occurs (like during high traffic times), that information could be helpful as well.

For more detailed troubleshooting steps, you can consult the Jetpack Boost documentation, which might have specific guidance for issues related to Critical CSS generation: What to do if you have problems with Jetpack Boost.

Please try these suggestions, and let’s start with checking for any plugin conflicts or server resource issues. I look forward to hearing back from you with your results or any further information you can provide.

Thank you!

Hello @tiffb,

Do you have updates about that? 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!
