Hello Mark,

I am sorry for the delay of this reply as it is a public holiday for us here. The reason that you are hitting this 404 error is mainly because you have a menu called "Pages" which is a text separator but it is using the same alias "pages", http://take.ms/Vjcti

To fix this, I have edited the menu item and given it a different menu alias, http://take.ms/WzAUU
