I recently got a trial certificate and used it for 1 month. When it expired I bought another and https://www.domain.com shows the lock and everything is great. When I access https://www.domain.com:81, the browser shows untrusted or expired certificate warning. when I look at that certificate it IS expired (basically it is using the trial certificate STILL). The ISPConfig server certificate did not change over like the one for the standard site. How can I fix this?
