I am trying to use the Donate Widget in the Blog module in SS 2.4. The widget adds okay but when I try to add a URL for a Paypal payment, the module truncates the URL rendering it invalid. I then tried a TinyURL shortcut which isn't truncated but when clicked seems to send an invalid link to Paypal. But strangely that same TinyURL when pasted into a browser directly works fine.
Is there a known design limit on the length of the URL for the payment field and if so, how do people get over this for Paypal payments?
