3.7.13 and My Calendar
 

I seem to have a problem with 3.7.13 and "My Calendar" plugin, which worked fine before.
Now in Grid View the location info produces a large block which overlays the calendar info and hides the events. List view works fine so I have defaulted the view to that.
The plugin author suggests:
"I'd start by checking out the settings for scripts on the Script Editor and make sure that the grid view scripts are enabled."
Not sure how to do that.
Site is knucklascommcentre.org.uk/event-calendar
To see the grid view before upgrading look at knucklas.org.uk/calendar
thanks for any help

I've now been told that the Script Editor is in the plugin, not the theme, so I'll close this thread for now at least.
