Continuum doesn’t allow text widgets to be added to the sidebar that don’t have titles. Put something in for the title of the widget (use a period or dash if you want it to work but the header to not be noticeable). Or, use the Continuum Unwrapped Text widget, which does not require a header and also does not wrap the content in a sidebar container (this is great for tall ads).
