Recently we noticed that many users who have designed their websites with WordPress are having issues with its accessibility with the www. WordPress sites are not working with www because we always install wordpress on example.com, not on www.example.com so if you browse Site www.example.com, it simply redirect/work on http://example.com, instead of http://www.example.com
Follow the below steps in order to fix such issues:
b)Go to setting
c)Click on general settings
d)You will get 2 options there, WordPress address (URL) and Site address
You need to put complete website address there, htp://www.example.com and thats all.
Now site will be accessible with www entry.
