blocked due to MIME type (“application/octet-stream”) mismatch I've been troubleshooting a memcache issue on our Drupal 7 site and in the process the front end CSS broke, meaning all content was unstyled.
The Chrome console has a message:

The resource from “/sites/all/themes/mbm/css/style.scss?qktcrf” was
blocked due to MIME type (“application/octet-stream”) mismatch
(X-Content-Type-Options: nosniff).

Should Drupal be using a .scss file on the front end?
If not, how would I determine where the breakdown of the .scss being converted to a .css file occurs?
Help appreciated.

Pretty sure that the scss files should be in a scss folder, and not the css folder.
/sites/all/themes/mbm/css/style.scss?qktcrf
