Or you can modified /etc/suphp.conf where change 'min_uid=500' to 'min_uid=48'
In Official kloxo that i use in my production server is not necessary to change the above suggestion.
/etc/suphp.conf file in production server
[global]
logfile=/var/log/httpd/suphp_log
loglevel=info
webserver_user=apache
docroot=/
env_path=/bin:/usr/bin
umask=0022
min_uid=500
min_gid=48
; Security options
allow_file_group_writeable=true
allow_file_others_writeable=false
allow_directory_group_writeable=true
allow_directory_others_writeable=false
;Check wheter script is within DOCUMENT_ROOT
check_vhost_docroot=false
;Send minor error messages to browser
errors_to_browser=false
[handlers]
;Handler for php-scripts
x-httpd-php="php:/usr/bin/php-cgi"
;Handler for CGI-scripts
x-suphp-cgi="execute:!self"
/etc/suphp.conf file in test server
[global]
logfile=/var/log/httpd/suphp_log
loglevel=info
webserver_user=apache
docroot=/
env_path=/bin:/usr/bin
umask=0022
min_uid=500
min_gid=48
; Security options
allow_file_group_writeable=true
allow_file_others_writeable=false
allow_directory_group_writeable=true
allow_directory_others_writeable=false
;Check wheter script is within DOCUMENT_ROOT
check_vhost_docroot=false
;Send minor error messages to browser
errors_to_browser=false
[handlers]
;Handler for php-scripts
x-httpd-php="php:/usr/bin/php-cgi"
x-httpd-php52="/opt/php52s/etc/php52s-cgi.sh"
;Handler for CGI-scripts
x-suphp-cgi="execute:!self"
;;; MR -- for using php52 just enough add 'AddHandler x-httpd-php52 .php' on .htaccess.
;;; it's make possible running 'dual php' on server!
Can the problem be related with the other differences between the 2 files?
