Remove unused CSS

I have the same issue

Hi all, please try to use our Critical CSS feature, here’s the instruction.

Hello,
I use this option, but it crashes my site.

How can fix this?

For crash your site, do you mean Flash of Unstyled Content? Please check on this article for more details.

You can try to turn OFF Generate Critical CSS in Backgroud then Purge the Cache to see does it work first.

I enabled Critical CSS but this error still exists.
