Drupal 8 – Css/JavaScript Files not Loading for New Installation

If you have installed Drupal 8 on Windows server and noticed the plain html website without Css/JavaScript, here is a way to fix the issue.

1. Go to plain html website. You will still be able to navigate to the website. Look for Administration > Configuration > Performance link.
2. Click on this link to open up a page which shows “Bandwidth Optimization” section. Unselect “Aggregate CSS files” and “Aggregate JavaScript files”. Click on “Save Configuration” button.
3. At this moment, you would get your site with Css and JavaScript but the main problem is not solved yet. So follow the next steps.
4. Go to DRUPAL_ROOT\sites\default\files folder. Create a folder “tmp” here so the final folder structure looks like DRUPAL_ROOT\sites\default\files\tmp.
5. Now go back to Administration > Configuration > Development > Performance page
6. Click on “Clear all caches” button.
7. Now select “Aggregate CSS files” and “Aggregate JavaScript files”. Click on “Save Configuration” button.
8. You should have got your Drupal website working with aggregated Css/JavaScript files.
