Thread:Project:Support desk/upgrading from 1.19.2 to 1.20.x Error: invalid magic word 'speciale'/reply (3)

In this file wiki-folder/languages/messages/MessagesEn.php the line exists in the magic words array:

'speciale'               => array( 0,    'speciale' ),

So I'm not sure why this error (Error: invalid magic word 'speciale') even comes up.
