Hello experts! I have been giving a piece of code to put on my website to provide my customers with a fees calculator. The calculator is run by an external website. When I input the <iframe code into html box on my website, I get an error message saying that the CoursePricer website has not been allowed on this website and that an admin needs to add this domain as trusted. Do you know how i do tis?
Sorry, but adding code to an HTML component is not a part of the Wix Code product (which is what this forum is about).
The basics of an HTML component is to put any HTML code in it. That code can be copied from Facebook, Google, or anywhere else, but you need to know the exact code to put there (which is not related to Wix Code)… We can’t really help with that. You will need to check with the supplier of the code.
You should make sure that the URL for the 3rd party service is https. This is required for security. If the URL is http only, you can change your site to http, but this is not recommended. See the article Enabling HTTPS for Your Wix Site for more information - but instead of enabling https, just disable it.
