Accounts status & recurring payment error

Hello,

I have a couple of problems that I can't seem to solve.

1. Member accounts do not expire. 1 minute, 1 day... it does not matter.

2. Even if I manually change the status of an account, it does not matter. The user can still access the site unless I manually delete the username and pass from the httpwd file.

3. I can not find the way to re-activate members account by paying for re-activation.. even if I redirect the expired user to the rediret page... that's it... where does the user need to go to pay for extening the service, and would that change the status of the account and reactivate the account?

Thank you!
