[MapServer-users] Error advises checking logs, but I am not sure what logs it's referring to

Hi Rob,

As you are going through OGR/GDAL you can get additional GDAL logging by setting "CPL_DEBUG":

MAP
  ...
  CONFIG "CPL_DEBUG" "ON"

See https://mapserver.org/optimization/debugging.html#step-3-turn-on-cpl-debug-optional
