This error appears if module such as NSP is configured to display an article or category which doesn't exists. Please check if You have not removed an article which still is set to show.
Fresh Install and I havent touched the articles or modules, just navigate around. I will go and check, this is something Gavick need to check its settings before releasing the quickstart files.
Sure. I'll pass this information to programmers, but can You please tell me where is this link to /new ?? I've been looking in the newest quickstart and demo of this template but it doesn't exists there I think. using such link gives a 404 Page not exists result.
