When looking at the Canvas Page, I see a list of posts.
Each title has a link.
Each link is broken because there is a missing space between the Canvas page URL and the permalinks structure that goes after that.
Here is an example:
On the plugin's page, The Facebook Canvas Page URL doesn't have a final slash because the documentation shows that it shouldn't be there.
So is this a case of updating the documentation or is there a slash missing in the code somewhere?
