We are having problems with members being able to renew. They are receiving the email notice to renew, but the link doesn't work (it goes to their account, but there is not a link there to renew). Also, when their membership expires, they don't have an option to renew. The only way I have been able to allow members to renew is to remove them from the database and let them sign up again with a fresh account (which is not the way it should work).
You should be able to access the account. I also have a screen shot from one member if that would be helpful. If you need to create a test account, please feel free to.
