Hi, @Moemen.

You can try clearing your browser's cookies and cache, or by logging in to your store through a different web browser altogether, or a completely different device. From there you can install the Facebook app again, to see if that will work.

You can also try installing the Facebook app on your store via incognito or private windows to rule out any browser issues.

Are you seeing any error messages, when you're attempting to install the Facebook app on your store?

@Kimi 

Yes error message tell me that this page are not exists which is very
strange and wired

Here the msg appears

There’s no page at this address

Check the URL and try again, or use the search bar to find what you need.
