Oh yes, since May 25, the Monobook design is no longer available. There is a new rule in Europe (GDPR) and FANDOM staff said that they can't support the Monobook with this new measure. You can read the official message by FANDOM here.

For the moment you can only use Oasis design, but you can keep an eye on Dev Wikia, maybe someone will add a script to keep the Monobook design.
