Templates do not load:: nginx

We have updated our zen cart to v1.5.3 on the server. Our server uses Apache and nginx. The templates will not load on zen cart v1.5.3 but they do on v1.5.1.

Zen cart is installed via Softaculous.

Is there anything within v1.5.3 that we need to allow in nginx for the templates to load?

Here is an example:
http://zctest.bieghler.net/zencart/

We figured out the issue.
In v1.5.3, it seems that Zen Cart will not load images if there is no SSL certificate installed on the domain when using nginx and Apache.
To remedy this, you have to comment out the line in /includes/configure.php:

define('HTTPS_SERVER', 'https://domain.com');

Once an SSL certificate is installed on the domain, the comment out must be removed.

It might be better to turn the SSL setting in the configure files to false.

Catalog:
// Use secure webserver for checkout procedure?
define('ENABLE_SSL', 'false');

Admin:
// secure webserver for admin? Valid choices are 'true' or 'false' (including quotes).
define('ENABLE_SSL_ADMIN', 'false');

// secure webserver for storefront? Valid choices are 'true' or 'false' (including quotes).
define('ENABLE_SSL_CATALOG', 'false');

Acenet:

In v1.5.3, it seems that Zen Cart will...

Just to clarify: There's nothing new to v1.5.3 that causes that.

The same problem will exist with any version ... because it's not a Zen Cart issue. It's just that your configuration is pointing to invalid URLs if you are using https without an SSL certificate.

So, yes, the solution is to supply correct URLs for the server you're working on.
