 * Failed to generate Critical CSS
 * Hmm, looks like something went wrong. We’re still seeing an unexpected error.
   Please reach out to our support to get help.
 * Have been getting this CSS error. Has to be the plugin as I’ve done literally
   nothing to my site. While I’m here, why is the CSS generator so slow when it 
   is working? It takes over an hour to generate my CSS.

 * Same problem. “See error message” produces
 * Internal Server Error
 * Just updated the Critical CSS a couple of days ago. Might be related to the most
   recent Jetpack update?

 * Hi [@damax83](https://wordpress.org/support/users/damax83/),
 * Could you please check for any errors in your browser’s console while attempting
   to regenerate Critical CSS using Jetpack Boost? Here’s how to do it:
    1. Go to _Jetpack → Boost_ in your WordPress dashboard.
    2. Open your browser’s console. If you’re using Chrome, press `Ctrl + Shift + J`
       on Windows/Linux or `Cmd + Option + J` on Mac.
    3. Ensure the Critical CSS feature is active, then press ‘Regenerate’ and observe.
 * If any errors pop up in the console, kindly capture a screenshot. You can use
   tools like Snipboard ([https://snipboard.io/](https://snipboard.io/)) or Imgur(
   [https://imgur.com](https://imgur.com/)) to snapshot and share the image. Please
   paste the screenshot link in your response.
 * We appreciate your cooperation!

 * Hey yeah there is an error. I’m blocking Jatpack from running somehow but I am
   not entirely sure why or how.

 * Hi [@damax83](https://wordpress.org/support/users/damax83/),
 * Thank you for the screenshot. Now, can you please try one more thing? Please 
   deactivate the plugins, all of them except Jetpack Boost, then navigate to Jetpack
   > Boost, ensure the Critical CSS feature is enalbed and click the “Regenerate”
   button to see how it goes (screenshot: [https://d.pr/i/7fzpW4](https://d.pr/i/7fzpW4)).
 * Looking forward to hearing back from you.

 * It is a live shop website, I can’t disable all of the plugins. Nothing would 
   work.

 * Hi [@damax83](https://wordpress.org/support/users/damax83/),
 * I realize that disabling all plugins on a live site isn’t ideal. How about deactivating
   the plugins one at a time and then using the “Regenerate” button in Jetpack →
   Boost to try regenerating the Critical CSS after each change? Alternatively, 
   if you can set up a clone of your site and provide us with access, we can investigate
   this more thoroughly. For this option, you can reach out to us privately using
   [the contact form](https://jetpack.com/contact-support/?rel=support&hpi=1).
 * Let me know how would you like to proceed so we can assist further.

 * Hi situation has resolved itself. I guess a plugin update somewhere fixed things.
   I can now re-generate CSS and you can close this thread.

   comes up!
