I built an e-commerce site based on wordpress and inserted the wordpress site through an iframe tag in my shapespark walkthrough, but the cache options of some browsers such as Google Chrome and Opera do not allow the changes that clients make to the pages to be saved cart or checkout.
Has anyone had a similar problem or how could I solve it?
The most common reasons for sites not working withing iframes is the X-Frame-Options: SAMEORIGIN header returned by the server. This is done intentionally to prevents all other sites from embedding such a site (see also a more detailed description of this header here: X-Frame-Options - HTTP | MDN)
I’m not sure if this is the problem also in your case, you can verify it by looking for errors in the Network tab for Google Chrome developer tools (F12).
