Regarding Error 404

[Mineshrai]

Hello,
When any one types wrong URL say for example www.mrmarket.in/hkyuf the browser is directed to error page 404. Sir I want if any one typed wrong URL or clicked any invalid links from search engines, then the browser should be directed to home page of my site. Plz tell me how to config it.

Thanx.

That's not part of vBulletin at all, it's a function of your web server. You can google "custom web server error pages" or check this link on how to make them:

This would be done outside of vBulletin. You could set your custom page to link to your forum homepage once you make it.
