Lenny, I answered you in the Premier forum.
For better, more accurate information from SLP support, could you please post your Plugin environment and url, (see Posting guidelines) I do not know if you have upgraded to the Power and Experience add-ons for instance, or what you have installed,/ activated.
to reiterate here:
The switch current map ID indicates that you have or had Multi Map plugin active. Multi Map was problematic and it is a third party add-on (Debaat forum ). Check to see if you have Multi Map active, deactivate and see if the problem goes away. Multi Map add-on as not been updated to work with the newer versions of SLP.
IS this a new domain? If so as of June 22, 2016 Google requires a Map API Key This applies to every plugin and every site that uses Google Maps API
