Error Notification Plugin: Need to disable text shown in share!

Hi,

I have this plugin installed, and it’s pretty good for what we wanted: Error Notification.

However, when sharing now we get this: https://trello-attachments.s3.amazonaws.com/551875a2c4f4da2ac49d5bac/499×511/0a07f04ccf213b9c6705d8646805c804/upload_2015-03-29_at_9.59.02_pm.png

How can we prevent this from showing in our page text for sharing?

Best,
Ivo
