If your app loads in the iframe but disappears after a few seconds and you see an error like “We’re sorry, this content cannot be displayed. Please try again later”, this means that your endpoint didn’t load the Wix JS SDK within 20 seconds.
There’s a few reasons this might happen. Here’s what to look for:
  • Make sure every endpoint in your app includes a reference to our Javascript SDK in the HTML document. 
  • If using URL redirect, make sure your app passes all query parameters to the forwarded endpoint. We don’t recommend using URL redirect, because it can cause errors.
  • Check if your app has the X-Frame-Options HTTP response header. This header may prevent the browser from loading your iframe’s content.
