Ah... interesting... I was advised to change the maps URL for the USA maps to "maps.googleapis.com" not "maps.google.com". Forgot I did that and it turns out the problem I was trying to solve had NOTHING to do with it. The Google servers went all "wonky" the other night and were throwing up erroneous "violation of terms" messages to random users.
3.9 will change this back & fix the problem, but that is a few days away.
In the meantime edit slp-adminui_mapsettings_class.php around line 524 (in get_map_domains()) and change this:
__('United States' ,'csa-slplus')=>'maps.googleapis.com',
__('United States' ,'csa-slplus')=>'maps.google.com',
For those that are not code hacks, 3.9 will fix it. You can always go back to 3.8.18 with the "Developer" tag on this page. Download the zip, deactivate slp (your settings/data will remain), delete slp, add new plugin & upload the 3.8.18 zip, re-activate.
