Push to wiki fails with "cannot run hooks/pre-receive" error

[J. Lewis Muir]

Hello!

I just tried to push a minor fix to the wiki, but I get the following
error:

---8<---
$ git push
Counting objects: 3, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (3/3), done.

 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to

Does anyone know what's wrong?

Thanks,

Lewis
