It appears you are looking for something which isn’t there. Either you have entered an incorrect URL or we have messed up. Why not visit our home page or alternatively, search for what you are looking for in the search box below.
Whilst a 404 error page does not send the visitor to the exact page they want, it can be used for a better presentation of your website. Offering the visitor other page options, alternate choice to go back and generally point them in the right direction is better than them leaving ASAP.
The 404 .htaccess error page keeps them on your site pages so that they are more likely to stay and find what they want on your site.

Once you have your 404 page setup, all you need to do is send visitors of incorrect url’s to this page. To do this just add the following line to your .htaccess file :
ErrorDocument 404 /404.php
Most often, the .htaccess file will be in the home root public_html folder on your server. This can change, for an example if you run you site or blog out of a specific folder within the public_html.
Alternately, You can place the 404 error template anywhere you want in a folder. For example you could place all error messages in a folder called errormessages refererring the 404 error to the url of the page.
ErrorDocument 404 /errormessages/404.php
That’s all there is to it.
