This question already has an answer here:
Please run below commands from Magento 2 root directory.
php bin/magento setup:static-content:deploy php bin/magento cache:clean chmod -R 777 var/ pub/static/
If it is still not running then...
Run following query in database
INSERT INTO `core_config_data` (`scope`, `scope_id`, `path`, `value`) VALUES ('default', 0, 'dev/static/sign', '0');
or if you have already value for that path, then change it from 1 to 0.
Then flush cache and deploy static content as follows.
php bin/magento cache:flush php bin/magento setup:static-content:deploy chmod -R 777 var/ pub/static/
