[MapServer-users] Silent error running mapserver

[Seth G]

Hi,

How are you setting your "PROJ_LIB" path? It looks like it can't find the Proj SHARE directory. 
Are you able to share a Mapfile? Maybe try with a cut-down version - there are lots of custom parameters in your querystring (that shouldn't affect things, but a simpler test case would be easier to debug).
