Checkout Redirect Loop when HTTPS Environment Variable is not Set


When using a payment gateway that requires SSL; upon moving to checkout the browser is stuck in a redirect loop.

Potential Errors

You may receive an error similar to:


The page isn't loading properly.
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

Google Chrome:

This webpage has a redirect loop


Too many redirects occurred trying to open “”. This might occur if you open a page that is redirected to open another page which then is redirected to open the original page.

Internet Explorer:

Cannot display the web page.

note: Some versions of Internet Explorer will continuously loop without displaying error

Known Cause

Some hosting environments do not declare that they are running securely in a standard way (or at all in some cases). This will cause issues with the is_ssl() to not be set properly. Shopp see’s that SSL is required and then checks for SSL. If is_ssl() is not set, Shopp will attempt to redirect to HTTPS. Thus creating a loop.

Known Fix

The current “proper” workaround for this is adding the following to your wp-config.php:


note: wp-config.php is located in the base directory of your WordPress installation.

This will allow is_ssl() to work properly. The need for this particular fix is due to some circumstances where is_ssl() is called before hooks are available.

  3. This fixed my issue after installing the ssl ticked. My site would not resolve requests to HTTPS.

  4. Apparently you can add this to the vhost config file for your site:

    fastcgi_param HTTPS on;

    But I solved it by using Mavis HTTP redirect plugin and specifying ‘checkout,confirm-order,thanks’ in the plugins setup page.
