Hi,

"no queryable layers found" is probably caused by something else though.

Make sure your LAYER definition contains something like (blank.html does
not actually have to exist):

  TEMPLATE "blank.html"
  TOLERANCE 0
  TOLERANCEUNITS PIXELS

For polygons, you probably don't want to set a tolerance (0), but for line
and point features you probably want to.

Best regards,
Bart
