Hi!
I have some fastcgi problems with the application of WDialog on a ubuntu
server 8.10 (virtual machine) and ubuntu server 9.04 (real machine).
I've tried to isolate the problem by using a simple example kept from
the WDialog example in wt-2.99.5 libraries.
I attach the source files.
It seems to be a server configuration error, because the application
works correctly on my notebook with debian installed, but I cannot find it.
I attach the file errorLog.txt with the firebug log and the
/var/log/apache2/error.log
Any suggestions?
Bye,
Stefano De Toni
