Next, check the file paths. A common error is to leave the location relative to another computer’s filesystem, eg:-

<a href=”C:\Documents\MySite\mysite.html”>Link</a>

This is incorrect as it refers to a file on your PC, not on our servers. File paths should either be absolute, eg:-

<a href=”http://mysite.com/mysite.html”>Link</a>

or relative, eg:-

<a href=”mysite.html”>Link</a>, if mysite.html is in the same directory as the page that it’s linking from.

Finally, check that there are no conflicts with other scripts on the site. Many major CMSes such as WordPress and Joomla use URL rewriting that will interfere with the correct operation of links.
