[mapguide-users] Migrating Mapguide 2.4 from Server2012 to 2019

[mg at maw-gis.de]

Hi Jackie,

that put me on the right track:

ERROR 4: `%MG_DATA_PATH_ALIAS[data_unmanaged]%Luftbilder/4442000_5470000.tif' does not exist in the 
file system,
and is not recognised as a supported dataset name.

After replacing the alias with an absolute path, it works.
Do you have an idea why this doesn't work properly on Server2019?

The alias works for all other data sources.
