Dear Manteiner and Larsen,
Im using Nagios4 on a fresh install with repo packages. I want to ask if
you fixxed that with:
"a2enmod cgi && apache2ctl -t && systemctl restart apache2"
I dont know if I have the same problem , but I have the problem when I
go to "host" and "services" CGI status file is going to be downloaded.
I do "a2enmod cgi && apache2ctl -t && systemctl restart apache2" , and
another module active as "rewrite" , and the problem continue , if this
is another problem , I want to know to open a new bugreport.
