When I create new blog posts they do not show up in the list of latest blog posts at my front page anymore. They do exist, I can browse to the posts by opening the blog.
A similar thing is the case for the list of the latest updated pages at the front page. It won't show my latest updated pages anymore.
I strongly suspect that this has something to do with that I recently changed the date and time format configuration. I have tried to change it back but I am not sure what the default settings are.
Can somebody please help me with this really annoying problem?
