Castos is unable to connect to the WordPress REST API for this site

Castos is unable to connect to the WordPress REST API for this site. Make sure your site is available over HTTPS and that no plugin is blocking the REST API.

If you're receiving the message above while trying to connect Seriously Simple Podcasting to your Castos account, this means that your site is either not available via HTTPS or that your site's REST API is not publicly accessible, potentially due to a third-party Security plugin.

In order for Seriously Simple Podcasting to integrate with Castos, you must use HTTPS and we need access to your site's REST API. If this is not feasible, you can still use Seriously Simple Podcasting but you'll have to create the episodes directly in Castos first and then manually recreate them in WordPress using either the embeddable Castos Player or the direct episode file URL.
