Events not showing for current month in Events+ calendar


Have got Events+ installed on our site ( and it works fine except for the fact that when you click on a link to the calendar from the home page menu it shows blank ( however if I click to go forward to another month and then back to the current month the events then appear (

The problem seems to be the url not including the date information for the current month when first viewing the calendar.

Am new to Wordpress and have no idea how to fix so any help greatly appreciated.
