Newly defined Classes are not showing up in PE console

Issue:
Newly defined Classes are not showing up in PE console.

Solution:
1. Check the logs at /var/log/puppetlabs/console-services/console-services.log.
2. if " [p.c.class-updater] 200 response received for request for classes in production." its most probably a syntax issue.
3. If it is 400 error then it is a connectivity issue.
4. In my case, i've written class in "/etc/puppetlabs/code/environments/production/modules/msgofday/manifests"  
CAPS.
5. I've changed that to SMALL letters and it works.
[root@example.com manifests]# cat *
class msgofday {
notify { 'hello, world!': }
 }
class msgofday::motd {
    file { '/etc/motd':
    owner  => 'root',
    group  => 'root',
    mode    => '0644',
    content => "hello, world!\n",
    }
 }
[root@example.com manifests]#
