Jetpack removed preprocessor for LESS CSS

Hi @oataki

Jetpack’s custom CSS was removed in favour of the site editor https://developer.wordpress.org/advanced-administration/wordpress/css/

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.

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 – just be sure to create a backup first.
