chantaloupe on "[Plugin: Events Planner] Excel Spreadsheet Error"

Hi Abel,

It seems I have another Excel spreadsheet issue. This time, when I click on the Excel icon, the spreadsheet that opens up only contains one cell that has "  " as the value. This happened before the update to WordPress 3.9.1, but didn't disappear after update.

Please advise,
Chantal
