Yes, thanks for your help with this.
I looked at the source and figured out what was happening. Basically, as you said, there was a </html> tag midway in the page and it messed everything up.
The problem is that I can't modify the widgets, because the page is messed up, and I can't remove the widgets either, because it's not an option yet.
I'll wait till you release the new version and try then. Thanks for this plugin anyway!
