I installed the facebook app for wordpress so that I can make posts in my wp site to show up in fb, but I have gotten a little lost in creating the app that I think is required. Currently I am getting this error message and the information being requested. I am not even sure I want, but if it is so that I can post using my android then the answer is no, I do not want to post to my WP site to display in FB.
You have enabled a Facebook Login integration for your app, but have not specified the Key Hashes. For security reasons, the Facebook application will not interact with any native application that does not have a signature that matches a corresponding key hash.
You have enabled a Page Tab integration for your app, but have not specified a Page Tab URL.
You don't need to complete the Android / iOS settings on the page. You just need to fill in the Web address and the application domain. If you remove the settings you don't need it should work (click on the x at the end of the box to delete the settings).
