Upgraded via admin, on composer installed Magento 2, upgrade reports success. Even though logo and menu and styles show, my store front page only displays this message, instead of the usual frontpage images. Everything is vanilla with sample products.
Error filtering template: Unable to write file into directory /var/www/html/magento2/pub/media/catalog/product/cache/1/small_image/240x300/beff4985b56e3afdbeabfc89641a4582/m/b. Access forbidden.

This message will appear if you run composer update but don't follow up with the magento setup:upgrade command. After ensuring that your file permissions are correct after the upgrade, go to the magento webroot and run this command:
php bin/magento setup:upgrade
Depending on your system permissions, you might need to use sudo.
