 * Hi,
   According to [https://jetpack.com/support/custom-css/](https://jetpack.com/support/custom-css/),
   may I know the reason why Jetpack no longer support Custom CSS including LESS
   preprocessor. As Jetpack mentioned few months ago that it won’t affect the LESS
   CSS that already written in the site but the CSS is broke after we’ve updated
   version of the Jetpack plugin. Do you have any suggestion about this? Because
   I have more than 500+ sites to manage and using LESS CSS compiler as the main
   CSS of the site.

 * Hi [@oataki](https://wordpress.org/support/users/oataki/)
 * Jetpack’s custom CSS was removed in favour of the site editor [https://developer.wordpress.org/advanced-administration/wordpress/css/](https://developer.wordpress.org/advanced-administration/wordpress/css/)

 * If you rollback to a version prior to 13.8 does the site start working again?
   If so, please can you add a screenshot (or paste the code you have in the CSS
   in Jetpack to a reply below)?
 * You can use this [plugin to rollback](https://wordpress.org/plugins/wp-rollback/)–
   just be sure to create a backup first.

 * Hello [@oataki](https://wordpress.org/support/users/oataki/),
 * 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!
