mystery posting location – help request!

Hi there,

Bit new to this and am in difficult position of having taken over mgmt of a site for a project half way… am finding my way round but have hit a snag in that i can’t work out where the ‘posts’ are appearing (they don’t seem to appear on any of the PAGES) they only appear on a ‘recent posts’ widget in the footer.
I understand a little bit of code but not much. Could anyone help me identify where my posts are being told to go?
I want them to appear on one page only and have looked in to how to do this, but they don’t seem to appear anywhere, which seems weird.

Any ideas on how to locate it much appreciated. Beth
