I was able to create Calendar Overlay in SharePoint 2010. My Calendar Overlay is not showing up properly (missing colorful boxes) when I add it to the Page ( Add Web Part > List and Libraries > Test Events) Below is what I see when I added the Calendar Overlay to my page.
But I'm able to view the Calendar Overlay just fine from the Lists option.
What's the best way to add Calendar overlay to show up on the page? Please advise.
