I'm aware the 'traceback' OpenLayers plugin error has been dealt with before, so apologies for raising the issue once again. Unfortunately for me, the solutions posted were way over my head, e.g. using workarounds and code posted on github, etc. I find it all mind-boggling.

If anyone could post a step by step answer for an absolute beginner like me I would be eternally grateful! Thank you. I hope that one day I can contribute something.

The error message reads:

An error has occured while executing Python code:

Traceback (most recent call last):

Safest way to start the openlayers plugin is to

  • set the project CRS to EPSG:3857
  • make sure on-the-fly-projection is enabled
  • add the background openlayers layer you want
  • load other stuff that might have other layer CRS, like WGS84 in lat/lon degrees
  • save the project
