ScriptAlias error in apache log

[Bob]

I just had reason to restart my apache webserver and noticed these 
errors in the log (I was checking the log due to another issue).

**/var/log/syslog
Jul 27 16:38:30 server apache2[30214]: [Wed Jul 27 16:38:30.563281 2016] 
[alias:warn] [pid 30232] AH00671: The ScriptAlias directive in 
/etc/apache2/sites-enabled/mailman.conf at line 4 will probably never 
match because it overlaps an earlier ScriptAlias.
Jul 27 16:38:30 server apache2[30214]: AH00558: apache2: Could not 
reliably determine the server's fully qualified domain name, using 
127.0.1.1. Set the 'ServerName' directive globally to suppress this message

There are two errors that I see. The first one is a ScriptAlias error 
and when I check 'etc/apache2/sites-enabled/mailman.conf', line 4, this 
is what it says 'ScriptAlias /cgi-bin/mailman/ /usr/lib/cgi-bin/mailman/'

I looked for another ScriptAlias that might be in conflict but am not 
sure about which ones are having troubles

**bob at server:/etc/apache2$ grep -sir "ScriptAlias"*
mods-available/mime.conf:    # To use CGI scripts outside of 
ScriptAliased directories:

/usr/lib/cgi-bin/mailman/
conf-available/serve-cgi-bin.conf:        ScriptAlias /cgi-bin/ 
/usr/lib/cgi-bin/

The second problem seemingly is the ServerName.

**/etc/hosts
127.0.0.1       localhost
127.0.1.1       server server.faithwalk.ca faithwalk.ca
#24.72.66.135   faithwalk.ca server.faithwalk.ca server

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

and

**/etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by 
resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search accesscomm.ca

I do not know how to change whatever it is I need to change to my 
resolv.conf so it reflects my actual nameserver or change the "serve 
accesscomm.ca" to the google servers.
