I've got a weird issue with the Blog Module archive widget. Originally my client wanted the page name and URL of the blog to be the same. The archive widget worked fine in the Sidebar as expected.
They then decided to alter the page name to a longer, more descriptive name, but retain the original URL. This change seems to have deactivated the archive widget - now the Sidebar just shows blog entries.
I've searched around for anyone with similar issues and can't seem to find anything. Has anyone come across this before?
