[mapserver-users] cgi-error: End of script output before headers mapserv

Also, if the underlying data is PostGIS, you should check the exact 
query being made against your PostGIS database (see the "CPL_DEBUG" 
setting at https://mapserver.org/fr/optimization/debugging.html ).  Once 
you get the exact query being sent to PostGIS, you can then connect to 
your database with psql utility and execute the same query, to make sure 
there is no problem.
