How to have access on debug mode in Canopy? When I try to activate it there pops up a window "simply log in on a canopy welcome screen to enable the debugger". But after doing it nothing happen then.
What version of Canopy are you running? To update Canopy to the latest version, please see this article.
If the problem persists (assuming by "subscribing" you mean "buying a paid subscription", not just "registering" for a free login), please email canopy.support@enthought.com
