I have the same problem in my website

I have the same problem on my website, and the site is now down several days

I made a few changes, one of them worked:

1. I renamed my htaccess file to htaccess_old
2. I disabled the plugin All in One SEO

I have the same problem.

I have the same issue, is there a way to find out how this is possible?

I have a same problem … and I see… No answer

Yes, almost 3 weeks and no response from the support… I think we have to switch to another extension.

Hello all,

We appreciate your patience while we work through these threads. The error message Failed to generate critical CSS can be difficult to narrow down as it often comes down to a plugin conflict or a setting on your server which redirects pages or content. Having an Under Construction or Maintenance Mode plugin can also cause this problem.

The message Failed to generate critical CSS is really just a general error message. On that screen where you see the message there should be a section where you can click to get a more detailed error message. Could you look for that error and perhaps share them here?

Hello,

I do not see a section with details (see screenshot), could you show me this with an image ?

Regards,

Axel

Hi @saleenf1 @renavail @eliograceno @igor997 @stevray

Thank you!

Hi @dual13 –

Thanks for sharing that screenshot. Sometimes there will be additional there that helps us to understand the issue.

When I tested our communication channel with your site, I noticed that your web server was responding slowly. I made an adjustment to how we communicate with your site which may fix the issue.

Could you try re-generating the Critical CSS? If you still get an error, the next thing to do would be to test for a plugin conflict.

The Health Check plugin’s “Troubleshooting Mode” is a good way to do this. It allows you to make changes to your site without them reflecting on the frontend. You can download that plugin here:

https://www.ads-software.com/plugins/health-check/

Once you’ve installed and activated the plugin, you can go to Tools → Site Health:

• Select the Troubleshooting tab and then click Enable Troubleshooting to automatically disable all plugins and add a new Troubleshooting Menu item in the toolbar at the top of the wp-admin dashboard.
• From here, you can enable and disable plugins and change the theme for your site, but without affecting normal visitors to your site.

Within Health Check, please disable all plugins other than Jetpack and Jetpack Boost and test again. If it works as expected, you know that the issue is with one of your plugins. Please enable your plugins one at a time, testing after each one, until you encounter the issue again. Once you do, you will know which plugin is causing the issue. At that point, you can either leave it disabled or reach out to the developers for a fix.

Hello @dual13,

Do you have updates about that? We usually close inactive threads after one week of no activity, but we want to make sure we’re all set before marking it as solved. Thanks!
