 * Is there any reason we can’t use the same App ID, App secret and App namespace
   on any/all sites on a WordPress Multisite installation?
 * Thank You, Steve

 * [@hakonzen](https://wordpress.org/support/users/hakonzen/), I’m currently using
   the same App ID, App secret and App namespace on several sites on my WordPress
   Multisite installation. Doesn’t seem to be an issue.
 * But I’d still like to hear from the WP community if this is going to be a problem.

 * It’s working for me. Steve – what is your App domain set to? [http://www.domain.com](http://www.domain.com)
   or domain.com?
 * If it’s set to www, technically that is a subdomain, so it won’t allow anything
   else other than the www. If you go into the app and change the domain to just
   domain.com, that will fix the othersite.domain.com issue.
 * Otherwise, not sure what the issue might be as it works fine for me.

 * You can use the same application info for more than one site if one of the following
   applies:
 * – All the sites are subdirectories under the same domain name (foo.com/a, foo.
   com/b, etc).
 * – All the sites use subdomains and you specify the Application Domain in the 
   Facebook app as the bare domain (entering “foo.com” as the App Domain will allow
   a.foo.com and b.foo.com to both work as well).
 * – Each separate domain name is entered into the Facebook Application as the App
   Domain (foo.com, bar.com, both entered into the application).
 * Basically, the Facebook Application must be able to recognize the domain of the
   current page that you’re viewing as being valid. Note that this applies to both
   the front end of the site as well as the wp-admin back-end, meaning that if you
   have a setup where they are on different domains, then the FB Application must
   know about them both in some fashion.
 * If the FB App doesn’t know about the domain, then it will fail to authenticate
   properly and stuff will seem to be randomly broken.

 * Otto:
 * And to use different FB applications for different sites in subdirectories using
   WPMU?
 * In my case, the subsites are totally different sites. I would use different applications.
