Sell URL is not valid

I’ve been trying to update the ggRhinoIFC plugin but I keep getting this error when trying to save the changes.

Sell URL is not valid. Says it’s optional and I deleted the form input contents.

Thanks in advance,


Hi Jon,

Which was the URL?


It’s empty. Here’s some images.

Hi John,

If you mark your App as a Trial/Commercial App, you need to add a link to a website where users can actually buy your App.



Ok, thanks. I’ll add a link. I might suggest you remove the word Optional from under the entry field then. Seems that compulsory data has a little red star next to it for all other fields.

Dear John,

You are completely right, we will modify the wording.
