Calendar not showing in dashlets

I cant see the calendar in dashlets, it is displayed in blank page. I have lot of messages displaying undefined as message also.
Also in calendar if i choose the next day it displays a blank page.

You probably have a number of issues to resolve. Start here:

  1. Turn off error logging in PHP - you’ll find numerous articles on the interweb advising on how to do this
  2. Make sure your permissions are correctly set for SuiteCRM
