In MediaWiki version 1.5 and later, the attribute to be set resides in LocalSettings.php and is as follows:

$wgEnableUploads = true; # Enable uploads

In older versions of the software, the attribute to be set resides in LocalSettings.php, but is backwards, i.e. $wgDisableUploads. The default is as shown:

$wgDisableUploads = true; # Disable uploads

Invert the value to enable uploads:

$wgDisableUploads = false; # Enable uploads

Configuring file types

You can add to $wgFileExtensions to allow uploads of any type of file you like. If not included then the $wgFileExtension line would look something like:

$wgFileExtensions = array('png', 'gif', 'jpg', 'jpeg', 'doc', 'xls', 'pdf');

You can also set

$wgStrictFileExtensions = false;

to allow most types of file to be uploaded. There are restrictions on some blacklisted filetypes.
