plugin version -1.7.1
When I go to the Shortcode UI settings page to make changes, and then save the changes, I am redirected to your Paypal donations page :)
I made a donation to see if you had a nifty system where by you had to donate some amount to be able to change settings (thought that would be cheeky but effective by the way)
However on redirecting back from the donation I just got an error page. So I assume this whole thing is an mistake :)
Useful plugin, cheers.
