I just uploaded Event Calendar Pro 0.0.1.3-b which fixes the html validation errors. There was also a validation bug in the DayPilot.dll which is now fixed.
One other change is from a community request. If only using one view (ie using List View and nothing else) then the link for that view is supressed since it is the only view available and the link is not needed unless you can navigate between views.
Best,
Joe
