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

Hi Jo,

Are you passing the problem extents to the shp2img utility?  Such as:

shp2img -m osm-transp-en-default.map -e -9.1433 38.7460 -9.140638.7487 -o ttt.png -all_debug 5

If that doesn't help, then I would start from the beginning: execute aGetCapabilities request and make sure you remove all "WARNING" messages.

    Hello Jo,

    I don't know this error as parameter-dependent...

    Do you get any error-output on the command line?
