CSS and JS are not loading on IDE site
Date Published: January 28, 2022
Issue
When you will open your IDE site, you may see that all the theming is missing from the site.
Resolution
This issue happens because the IDE uses https and the resources(CSS & JS) are called using http. To resolve this issue, you need to remove the https from the IDE URL and load it with http. Changing the Web IDE address to http://... (removing the s) will solve this.
Cause
This issue is occurring with Drupal 7 sites only because of mixed content issue, detailed information regarding this is available here https://www.drupal.org/https-information
