View, Edit, and other links not showing up on content items when using www.

You will see that in www version, you are not logged in.

There are many ways to overcome this. Setting cookie domain and a www redirect will solve this.

You can make use of configuration in .htaccess file of drupal

# Various rewrite rules.
<IfModule mod_rewrite.c>
  RewriteEngine on

  # If your site can be accessed both with and without the 'www.' prefix, you
  # can use one of the following settings to redirect users to your preferred
  # URL, either WITH or WITHOUT the 'www.' prefix. Choose ONLY one option:
  #
  # To redirect all users to access the site WITH the 'www.' prefix,
  # (http://example.com/... will be redirected to http://www.example.com/...)
  # adapt and uncomment the following:
  # RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
  # RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
  #
  # To redirect all users to access the site WITHOUT the 'www.' prefix,
  # (http://www.example.com/... will be redirected to http://example.com/...)
  # uncomment and adapt the following:
  # RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
  # RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]

Else you can create a setting in the vhost in apache or httpd as

<VirtualHost 192.168.2.1:80>   //your ip address
     ServerAdmin abc@xyz.com //your email
     ServerName mysite.com
     ServerAlias www.mysite.com
     DocumentRoot /var/www/mysite
<Directory "/var/www/mysite">
allow from all
Options +Indexes
</Directory>
     ErrorLog /var/www/logs/error.log
     CustomLog /var/www/logs/access.log combined
</VirtualHost>
