[Corrado Monteverde]

Warning: MapScript: Unable to initialize module Module compiled with 
debug=0, thread-safety=1 module API=20001214 PHP compiled with debug=0, 
thread-safety=1 module API=20000809 These options need to match in 
C:\program files\Apache Group\Apache\htdocs/mia/gmap3/htdocs/gmap75.php on 
line 34


does anyone know this kind of error message I get and how I can resolve it?

thanks

Corrado
