I closed the store due to a registration attack - then i installed the gooogle recapcha add-on.
Turned store back on - the new registration form showed the text recapcha challenge, so I assumed it was working - it allowed a test new registration.
Refresh the store and the recapcha challenge is no longer there.
Then I realized I didnt configure the recapcha settings - so registed with google got the keys and set up the recapcha options in admin add-on panel.
There is no recapcha challenge or checkbox on any form???
Any advice much appreciated,
