When I activate "Custom 404 page contents" the content of "Custom contents" becomes only the title of the error page, not the content.

What can I do to fix this?

"404 page override mode" is on, "Custom contents type" is "HTML"

EDIT: Joomla 2.5.28!

Hi probably it depends on the template used,

check that the file error.php includes the call to the getMessage function as the default Protostar

$this->error->getMessage()

Cheers

There is an error.php in the "system" template folder, which contains "$this->error->getMessage()" three times (title meta tag, title of error box and as a part of the content under "Technical info" ).

I guess I first have to create my own copy of the error.php in my template folder.

EDIT: OK, this works, but the possibilities are very limited, so I now use a completely different way of creating my own error document (via an article, modification of PHP code in error.php and in .htaccess).
