WordPress Address www. or none www.
How to get www. before your domain name on your WordPress Website.
If visitors type to www.pinguisweb.com or chose to type pinguisweb.com they will still find the Number 1 “Website Design Kerry” website.
In fact when you visit www.pinguisweb.com, the www will not be displayed in the browser’s address bar.
Its assumed when you are searching the world wide web that www. is there.
As long as the domain name is identical there will be no problem with WordPress. Its written into the .htaccess file WordPress has Rewrite Rules to correct this.
To change to either on the left hand black bar go to settings and general. Basically its a matter of choice.
Just be consistent throughout.
Of course, WordPress changes everything when you go installing it in a sub domain and linking it back to you main domain.
