Hello,
I've just installed Magento 2.3 and the installation went to its term.
However when I try to access the Magento store or admin, the page is loaded but the css/js are not loaded.
Example
https://magento.mydomain.org/pub/static/version1544234356/adminhtml/Magento/backend/fr_FR/extjs/resources/css/ext-all.css
Leads to a 404 page.
If I look at pub/static I don't see the version1544234356 directory
# ls magento/pub/static/
.htaccess adminhtml deployed_version.txt frontend
So why Magento tries to access the version1544234356 directory ? The problem is there.
