How to resolve Google Maps python error?




How to resolve Google Maps python error?

There are times when I want to activate Google Maps after having activated a few layers but this Python Error message comes up. I am no programmer so do not know what is happening? Deleting the vector files also does not remove the message. However closing QGIS and re-activating QGIS seems to solve that problem. It seems like Google Maps wants to be given first go then everything seems alright. Do not ask me why but so far, closing QGIS and switching it back again does the trick.

  1. That's a bit hard to do with just a picture. It would be nice if you post the actual error messages, too.

  2. Error:latitude or longitude exceeded limits....looks like coordinate out of range.. maybe problem with datum transformation from rso kertau to wgs84. Your coordinate kat bawah tu looks like RSO..
