In a single SSL site it´s works fine. However, if we have more than one SSL site in the same server, this plugin only check one of them, and all the sites has the same expiry date.

Thanks.

After trying a bunch of other ssl cert plugins, this one works right out of the box on a minimal install O.S. Thank you very much!
