Public calendar suddenly empty

Public calendar suddenly empty

My public calendar is empty when I look at it, either weekly or monthly .  I can see events in my personal editable view.

Firefox (Windows 8) and Chrome (MacOS).  In the developer console there's a JavaScript error, suggesting corrupted data. Is there some way I can find and clear it?

For the monthly view the error is

zohocal.js?1414049310586:1 Uncaught TypeError: Cannot read property '1232956000000009003' of undefined

For the weekly view it says
