Bitnami installations on Google Cloud hosting frequently experience problems with file permissions. If your site is showing many 404 errors in the console and not loading stylesheets properly, then setting the file permissions again can solve the problem:
sudo chown -R bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/wp-content
sudo chmod -R g+w /opt/bitnami/apps/wordpress/htdocs/wp-content
The theme is quite old and no longer sold with support included. How ever if you still have active support remaining on ThemeForest then you can use the form on the left or contact via ThemeForest.
