I dont have an error page. http://postimg.org/image/uur5pm25z/
Googled it, joomla! have its own documentation, but it says copy error.php from the templates/system directory, to template directory. But there is a file named error.php in templates/startuptemplate.
I have modified error.php in the templates/startuptemplate WITHOUT copying error.php from system directory, but still dont have an error page.
Downloaded The Qlue 404 extension component/plugin. It is not working either.
What to do folks
