A clean installation of Drupal 10.1 does not create CSS/JS cache files, but does reference them. This leads to a broken site when caching is enabled. This does not happen on a clean installation of Drupal 10.0.0.
Installation:
composer create-project drupal/recommended-project drupal
cd drupal
composer require drush/drush
Open web interface and do a standard installation. Everything works correctly during installation.
Issue: At the end of the installation, the site loads with a broken interface.
Why: The cache is enabled by default but does not work. Aggregate CSS and JS files are referenced that doe not exist. The sites/default/files/css and sites/default/files/js folders do not exist. Any referenced CSS or JSS file are never created.
Testing: Clearing the caches either through the web interface or with Drush does not resolve the issue. The cache folders and files are never created. Manually creating the cache folders does not resolve the issue either. Files are still never created.
Workaround: Disable the CSS and JS aggregation under Config -> Development -> Performance
Note, doing the exact same installation, but using version 10.0.0 works perfectly. It's only 10.1.0 that seems broken.
Server info:
OS: FreeBSD 13.2
PHP: 8.2.8
Web: Nginx
App server: uWSGI
Create proper cache directories and aggregate CSS/JS cache files.
Closed: works as designed
10.1 ✨
