If Clickker is running in a virtual environment, make sure Clickker is disabled on the old virtual server before transferring to a new server and a new API key should be requested.
For all moves of Clickker to a new server, it is always first disabled on the old server and then a new API key is requested.
On a completely new server, Clickker should also be reinstalled including a new API key.
In all cases, it is wise to contact us for this!
