since the rendering of a XOOPS site is largely controlled by the user's browser, and its support of modern web standards, I ask what browser you are using to access the site? This problem is typically displayed in a browser like IE 5.5 or IE 6 when the XOOPS site is wrapped by a frame page.
If you are using a frame page to display xoops, what is the full html for the frameset page?
