Critical bugs found in latest update 4.0.5 "Cannot Accept Payments!!!"

Hi guys,

your latest update of play plans version 4.0.5 has broken couple things we have found.

we can no longer accept payment now. When you click on check-out on any membership

it says: "Empty password not allow"

As a result our sales has completely come to halt. Also when you click on components > payplans > apps we can a error 404
the problem with that one is you have changed the URL from apps to app

this could be the reason why other things are broken as well

Please fix this issue asap...
