Publish to a Test Facebook Page: Because there are many different applications that you can create using Social, the best way to test or troubleshoot an application is to publish it to a test Facebook page.
If you publish a newly created application to a test Facebook page before publishing the application to a public-facing page, you can then test the application to ensure that it functions the way you expect and to ensure that the correct information is being collected by Form elements. If you collect form data with an application in a test environment, you can clear its data before publishing the application to a public-facing Facebook page. See Manage Application Results.
For information about the different elements you can use in an application and how to configure them, see Add and Configure Elements.
Rigorously Test Your Custom Style Sheet (CSS): If your application uses a Custom Style Sheet (CSS), ensure that you rigorously test the application. The CSS is advanced functionality. Please use at your own risk. Customer Support does not provide assistance with Custom Style Sheets should you encounter problems. We recommend rigorously testing your applications when using any custom code. For more information, see Using Custom CSS.
Ensure that Your Application is Configured for Mobile Devices: If you are having trouble with an application's layout on a mobile device, see Mobile Device Considerations.
