I created a Facebook page for my website, and I have added the like button to various product pages. Whenever I load the page, I get the error that I need a valid app ID. So I created the app and added the website as a platform, but I keep getting this error:
Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.
I'd like to know:
- If I just want a like button on my page, do I really need to create an app?
- If so, what does the above error mean?
Thanks, Rick
