Facebook not working on my MAC

Today, my girlfriend came to me saying facebook doesnt work on her macbook. However, all other websites work perfectly fine.

Well the perfect and easy way to make it work:

1. Are you thinking something wrong with network ? ( Nop )

Well your network is probably running fine unless you have blocked it from your router or similar device.

• Open Terminal on MacBook 
• Type sudo nano /private/etc/hosts
• Enter password
• The file should be similar to this 

##

# Host Database

#

# localhost is used to configure the loopback interface

# when the system is booting.  Do not change this entry.

##

127.0.0.1       localhost

255.255.255.255 broadcasthost

::1             localhost

fe80::1%lo0     localhost

If there are any more entries delete them .Finally, save the file using control X .

Lastly, type command dscacheutil -flushcache 

Hurray !!!!!!!! your facebook should work now.
