In the recently-created Tulu Wikipedia (T140898), the Tulu language doesn't show up in the Content Translation dashboard article selector:
Notice that the second dropdown is empty. I guess that it's a misconfiguration somewhere.
ContentTranslation (CX) configuration is mentioned in the wiki creation procedure. If the procedure was was simply not done completely yet, then I can wait patiently until it is (T140898 is still open). If this was done, but something didn't work correctly, the procedure should probably be fixed.
Thanks!
