Hi I had installed magento2 with sample data.
I would deploy static css/JS but the command php bin/magento setup:static-content:deploy it return 0 error but the problem still here.
Also I can't find deploy.php file in the standard dir.
Can you attach the screenshot of error you get after clicking php bin/magento setup:static-content:deploy? Are you running your project on Linux or Ubuntu?
deploy.phpwas used in magento1, which has been removed in magento2 so that commands are consistent with Symfony's CLI.
