Details

Files with these extensions will never be allowed as uploads.

$wgFileBlacklist 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';
$wgFileBlacklist = array_diff( $wgFileBlacklist, [ 'exe' ] );
$wgMimeTypeBlacklist = array_diff( $wgMimeTypeBlacklist, [ 'application/x-msdownload' ] );
