Problem: InfoPath Items not showing up in Form Library.
1. Go to Form Library Settings > Advanced Settings and “Allow Management of Content Types”;
2. Click the “Form” content type and then Advanced Settings. In the next screen, click Edit Template to open the Form in Edit mode in InfoPath;
3. Right click the Submit button and click Properties;
4. Click Submit Options > Manage > Modify and check the Document Library path to ensure that it is pointing to the Library only and nothing more.
For example: http://servername/sites/testingworkflows/Derek%20Travel%20Form%20Library/Contact Me link in the top menu.
