[ecoll]

i've a big problem

i try to install awstats
when i test http://localhost/awstats/awstats.pl?config=my_domain, i see the script on screen.
i've try to install mod_perl

now on my all domain  i see the centos7 Apache HTTP Server Test (/usr/share/httpd/noindex/index.html)


i've test to rebuilt vhost, re-built apache but nothing change
it looks like apache no longer handles vhosts

Check if by mistake you installed another version of apache. You remove httpd
