It seems you have a syntax error in the line 60 of your
/opt/bitnami/apps/opencart/htdocs/catalog/controller/module/postcode.php file. Probably the file has a
} where it shouldn't. Could you try to edit it, in the same way, you did with
httpd.conf using emacs?
I would recommend to do a backup of the file before starting to edit. For that, execute:
sudo cp /opt/bitnami/apps/opencart/htdocs/catalog/controller/module/postcode.php ~/postcode.php-backup
You could restore it executing:
sudo cp ~/postcode.php-backup /opt/bitnami/apps/opencart/htdocs/catalog/controller/module/postcode.php
