Hey dagyboy,
I really appreciate your support and that youre using this plugin.
I also wants to apologize for this issue, and any other issue you might have found.
Sad part is that I don't own any visutella plugins by myself. It might be some sort of incompatibility between those plugins.
I'll be back to you in case I found out what's the problem is.
As a general rule, always test new plugins in a blank-or demo project.
