Thread:Project:Support desk/'invalid magic word 'rootpagename (2)/reply (7)

I confirm the same behaviour on my installation. Web upgrade from 1.20.2 to 1.22.0 results in the bespoke error:

"[642fd5f3] /wiki/index.php/Main_Page Exception from line 316 of /var/www/mediawiki-1.22.0/includes/MagicWord.php: Error: invalid magic word 'rootpagename'"

and same stacktrace as written in first post.
