How to fix its MIME type ('text/html') is not a supported stylesheet MIME type error in Magento 2

To fix this MIME type issue:

Solution 1

1. Go to file path pub/static/

2. Check whether the .htaccess file is available (hidden file - Press ctrl+H to view it).

3. If not available, you can download .htaccess file in the file path pub/static/ and move it into your server.

4. Finally, clear your browser and Magento 2 cache and check again.

Another way if .htaccess is present in pub/static folder try to redeploy static view files by running:

php bin/magento setup:static-content:deploy -f

Solution 2

Double-check that you have installed all requested PHP extensions.
