“Hey! Caps lock is on” error message

Hi there,

I have the latest version of your plugin installed on my website. I am using the shortcode to add the print button to my pages.

Whenever I click to print my page, the print-friendly window comes up and all my page appears to say is the site URL, the site name and “Hey! Caps lock is on.”

Caps lock is not on for my computer and I have a co-worker who is experiencing the same issue. Do you have any thoughts on what could be causing this?

Thank you so much!
