Need to add a Blog to site. I've done this once before without problems. I've downloaded master files for 'blog' and 'widgets' and placed in root directory. Done the dev/build and ?flush=all and I can see an item called 'Blog' in my navbar (no entry telling me module has been successfully installed however). When I click the 'Blog' link I see the parent directory and associated files therein.
I obviously missed something really basic but can't see it? What gives?
