We have an unlimited license for the User Role Editor Pro. Randomly we will get emails from our sites saying that the license is invalid. This tends to happen pretty frequently, with no pattern, some sites more often than others.

Obviously the fix is simple – we just go in and deactivate the license, then enter the license key again and reactivate it. But when we’ve got 30+ sites (so far) using the plugin – this gets rather tedious.

How can we keep this from happening? Thanks!
