Apache v.1.3.12 & PHP-4.0.5 - Apache does not execute my PHP scripts, I get a white page

Hi, I installed apache v1.3.12 and PHP-4.0.5 on my Solaris 2.6 machine. It was working normally since June 2001. Suddenly, apache has stopped to execute my PHP scripts. Instead to get my "Hello World" PHP message I get a white page only. Do you have any idea why my PHP scripts cannot be executed anymore? I tried to reconfigured both apache & PHP, but still it the same. Below is a list of all modules included in the current httpd file. bcad7# ./httpd -l Compiled-in modules: http_core.c mod_env.c mod_log_config.c mod_mime.c mod_negotiation.c mod_status.c mod_include.c mod_autoindex.c mod_dir.c mod_cgi.c mod_asis.c mod_imap.c mod_actions.c mod_userdir.c mod_alias.c mod_access.c mod_auth.c mod_so.c mod_setenvif.c mod_php4.c suexec: disabled; invalid wrapper /usr/local/apache/bin/suexec Thanks, Atif
