Magento 2 does not load css or js after setup: upgrade - magento2

Question

My website is in default mode only. After run "setup:upgrade" my web does not load the resources css or js. "Refused to apply style from '' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled."
Any idea what might be causing this problem?

Answer 1

If you are using Linux then change the mode to developer and then run php bin/magento cache:flush from the document root of the webserver.
If you are using Windows then please follow the below steps:
change the mode to developer
run php bin/magento cache:flush from the project directory
run bin/magento setup:static-content:deploy -f from the project directory
Please let me know how it goes!

Answer 2

Try this
sudo su
cd /var/www/html/magento2
Set permissions to the files as follows
find . -type f -exec chmod 644 {} \;
Set permissions to the directories as follows
find . -type d -exec chmod 755 {} \;
Set permissions to special directories: as follows (these commands solve your file uploading issue)
find ./var -type d -exec chmod 777 {} \;
find ./pub/media -type d -exec chmod 777 {} \;
find ./pub/static -type d -exec chmod 777 {} \;
