Details

Files with these extensions will never be allowed as uploads.

$wgProhibitedFileExtensions overrides $wgFileExtensions , so you must remove an extension from the blacklist before you can upload files that have it. For instance, to allow users to upload executables, add this to LocalSettings.php :

$wgFileExtensions[] = 'exe';
$wgProhibitedFileExtensions = array_diff(
    $wgProhibitedFileExtensions,
    [ 'exe' ] 
);
$wgMimeTypeExclusions = array_diff(
    $wgMimeTypeExclusions, 
    [ 'application/x-msdownload' ]
);

This configuration parameter used previously was $wgFileBlacklist .
