- Login to WP, and select edit (posts or pages)
- Put your mouse over the title of the page or post you want to know the ID of, and look at the browser status bar at the bottom. The number at the end of the url is the post or page ID.
- You can also click the title of the post or page and look at the url in the address bar. The last number in the url is the ID.
When entering in these IDs into the options page on the FCG plugin, enter them in with commas, but no spaces.
Hope this helps!
