I understand. I'm sorry to hear this.
Maybe you should mention this somewhere in the documentation, that this widget is not compatible with hosting at One.com? I didn't think there would be an issue such as this, and it would have been nice to know before I purchased the template. Maybe others after me will come in this situation.
I'll see if I can change my hosting, because I really like the design of your template. It as the reason I switched my site from SquareSpace to WordPress - do you know a hosting that is compatible with all your plugins?
