Plugin not working

This morning this plugin and all my spreadsheets were working perfectly. Then I updated a number of other plugins (not this one, and since WordPress doesn’t keep a log of recently updated plugins, I’m not certain which ones I updated). About an hour later I noticed that none of my google spreadsheets are showing up, no error message, just blank screen.

Here’s an example page that should have three spreadsheet showing:

Can you provide a cause/resolution?
