Hi,
I have not seen what you describe.
Is it on a development machine or a productioon machine?
What version of mojoPortal?
What db platform?
If it happens a gain can you copy and paste in some of what you see?
ASP.NET has a trace feature that can render debug info in the footer of the page but it typically is enabled or disabled in Web.config, I've never seen it spontaneously activate.
Without actually seeing what you are seeing I'm not sure whether it has anything to do with the trace feature. Need a screenshot or at least some of the text.
