as in the image below when a pge has little content like the categories page the menu in the profile tab from the toolbar of easydiscuss expants vertically but i does not shift the page it collapses behind the footer must be a z-index issue maybe?
It seems like your current template styling set those content if appear on over the footer area, it will set to hidden.
I already applied some temporary css custom fix into your template css file JoomlaFolder/templates/shape5_vertex/css/template.css
