After installing magento 2.1, css is not loading and it is showing version number in css path which results in 404. See below url:
http://exapmle.com/pub/static/version1497424536/frontend/Magento/luma/en_US/css/styles-m.css
instead of above it should be
http://exapmle.com/pub/static/frontend/Magento/luma/en_US/css/styles-m.css
I have followed all steps i.e. upgrade, compile and static content deploy. Also apache configuration is fine and allowoverride is all there
Try this Before that take Backup
Remove everything, except .htaccess file from pub/static folder
Open up app/etc/di.xml find the path “Magento\Framework\App\View\Asset\MaterializationStrategy\Symlink” and replace to Magento\Framework\App\View\Asset\MaterializationStrategy\Copy
Note: Remove entire files and folder under pub/static except .htaccess file.
