Page sense snippet testing not responding

Page sense snippet testing not responding

Hello
I have a Pagesense snippet on this site https://profitsavvy.org
It seems to be correctly installed.
When I click 'verify snippet' it opens a test window but there is no response.
When I do the same thing with a site that does not have a snippet it does the same thing but then responded to say "snippet not found".
I have run the applciation for several days without logging any responses so I belive the snippet is not working properly.
Can anyone assist?
Thanks
Scott
