Drupal Installation Default Page not loading css

Question

I recently installed Drupal on Windows Server I had no errors on installation. There was a warning for OPCaching. I also don't think it should affect it but I used SQLite.

After installation the default page loaded with no CSS. Does anyone know why this happened or how to fix it?

Answer 1

I faced the same issue with Drupal 9. To resolve this I followed below steps:

1. Navigate to /admin/config/development/performance in your browser.
2. Under BANDWIDTH OPTIMIZATION, Uncheck Aggregate CSS files and Aggregate JavaScript files checkboxes.
3. Click on Save configuration.

This way the default/enabled theme will be loaded. I Hope this will help !
