I have a website which was built on Wordpress and Woocommerce
Main site: domain.com
Staging site: staging.domain.com
Source code run on docker : WordPress:4.9.7-php7.2-apache
I use theme Flatsome, some days ago, I upgraded Woocommerce, everything worked fine, but only Visual Editor was blank.
Then I cloned DB from live site to the staging site and rollback code, changed the theme to 'Twenty Sixteen' but the Visual Editor still is empty now.
Mysql is same, Webserver is same, because it runs on docker. But the Visual Editor does not work
