After publishing a new post I get redirected to a view that shows my blog with the new post, and on the left there's a sidebar with suggestions and info about my post (perhaps this is only shown on blogs with few posts).
It says, "You published 3 posts" where 3 is the current number of posts I have published so far. It should say "[...]have published 3 posts" and not "[...] published 3 posts." As it is now, the wording suggests that I just now published 3 posts rather than 1 post. The "have [verb]" construction should be used when you're talking about an event that's happened during an unspecified time (period) in the past. Simple past is for time-specific events.
The blog I need help with is afoolscritique.wordpress.com.
