Steps to replicate the issue (include links if applicable):

• Upload a file
• Choose a license > Dies ist die Arbeit von jemand anderem und ist frei zu teilen (This work is by a different author and free to share) > Enter a license as Wikitext

What happens?:
The following error is put out: "Der eingegebene Wikitext enthält keine gültige Lizenzvorlage." (The entered wikitext does not contain an allowed license template). The error did not occur until yesterday.

What should have happened instead?:
The error message should not appear (the preview gives out a proper license tag)

Software version (skip for WMF-hosted wikis like Wikipedia):
