If you go to their site for help, they'll make you purchase a membership before they tell you a fix or work around. This sounds like a scam. Either fix the issue or state the product as commercial.
You have to disable jSecure, then logout, then log back in via the default back end url. I've tried disabling and re-enabling the modules in different order and still the same result.
It's been over 5 days after posting the issue on the jSecure forums/support without even a reply saying that they will look into it. I don't expect a solution right away, but they could at least reply saying that they will look into it.
This product definitely would receive five stars if not for lack of support. Again, for the price I don't expect much, but at least a reply that they will look into it.
