Navigate to your database and perform following steps:-

  • Find core_config_data table and open it.
  • Add a new row and provide "dev/static/sign" under path and "0" under value (without quotes) and leave other fields unchanged and save it.
  • flush cache php bin/magento cache:flush
  • perform static content deploy php bin/magento setup:static-content:deploy
