UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Access rights, CGI library ?

I have installed UBB 5.47e OK on a hp-UX 11.0 trusted system.
When installing UBB 6.0 I fail in the ubb6_test.cgi script; the script runs OK from root, but coredumps when run as a regular user. It does not coredump when I remove the lines "use CGI ':standard';" and "use CGI 'qw(:cgi_lib)'" (but then it obviously has very limited functionality).
