Incorrect directory permissions.
Make sure that the latest microupdates are installed. If not, apply the latest Plesk microupdates.
Restore virtual hosts permissions using following the instructions for the installed Plesk version provided in Plesk Knowledge Base article:
#6572 - How to restore default permissions in the virtual host directory
In case the issue still exists, manually check permissions for the directories. Correct the permissions, if necessary:
# chmod 0755 /var/www/vhosts/example.com/httpdocs/components/com_virtuemart/shop_image/product/
