Mapserver returns blank pages

[Umberto Nicoletti]

I presume you are running php as shared module, right?

If so recompile with this configure flag: --with-threads and then make
sure you read the thread safety FAQ:
http://mapserver.gis.umn.edu/docs/faq/thread_safety

If you plan to use unsafe components (like cartoline symbols) switch
php to cgi mode (and then you can avoid using the --with-threads
option).

HTH,
Umberto
