i updated my html page but for some reason its not refreshing/showing new content.
Its a custom page made in the node tree. but when updating the html with some new content it simply does not show the new content. it stays the same. http://cupcakethunder.eu/index.php?pages/AboutUs/
Have you edited the page template directly via Appearance -> Templates : _page_node.# ? Making changes directly to the page template on your style would override any edits done in the Applications -> Node Tree -> Page Options -> HTML I believe.
