You have deleted your .htaccess file from **pub/static/.htaccess**

please unhide files on that folder if check if available, else copy it from another magento setup and copy - paste it on "pub/static/ HERE "

then follow below commands.

 1. `sudo chmod 777 -R var pub pub/media app/etc`
 2. `php bin/magento setup:static-content:deploy`
 3. `php bin/magento cache:clean`

Hope this will help you.
