Sometimes when we upgrade CalendarBudget, your browser holds on to the old version of the code in the browser cache and gets confused, resulting in a blank screen. Most often, this can be resolved by clearing the cache.
 
You can clear your cache by following the instructions here:
Clear Cache Instructions
 
After clearing your cache, reload CalendarBudget. If the problem persists, please open a support ticket telling us which browser you use and details about what’s happening.
