Thanks for your reply Otto. I was away on vacation, but I'm back now and ready to tackle this so my metatags work.
Every time I try to click on these two links on your setup page:
Can't find your key?
Get a list of your applications from here: Facebook Application List
Select the application you want, then copy and paste the Application Secret and Application ID from there.
Haven't created an application yet? Don't worry, it's easy!
Go to this link to create your application: Facebook Application Setup
After creating the application, put http://anniehearts.com/blog/ in as the Site URL in the Website section.
it redirects me to my FB fan page:
So I tried to go to from there to my apps page, but all I get is the apps I already have. There's no option to add new apps. Even if there was, I don't know which one I should choose.
Any help is appreciated!
