We have issues after switch to production mode: no work any style css: Gerris.pl
1.Clear content from directory var are:
var/cache var/di var/generation var/view_processed
2.Clear content from pub directory except .htaccess file.
3.Now run command forcefully because in production mode content not automatically deploy like developer mode so here we need to use -f after command.
php bin/magento setup:static-content:deploy -f
