Hi Melissa,

This happened because you renamed two of the issue tracker fields to the same name, "(Admin Only)". I was able to get to the admin page on your server (it still worked OK, but the error prevented us from showing the button to get there, meaning you had to know the right URL) and reset the names to the default. It's working normally again.

I'll open a bug to prevent this problem in the future, but for now you should be OK if you don't reuse the same name for multiple fields.

Thanks,
Josh
