Build error (999) - "Conf file missing"

[Shareef Dabdoub]

Build status: https://readthedocs.org/builds/phylotoast/2924777/

Relevant part of the build message:

checkout

-----

Failed to import project; skipping build.

Error

-----

Conf File Missing. Please make sure you have a conf.py in your project.

This is a Sphinx project that was renamed on GitHub, so I deleted the original RTD project, and created a new one with the new name. Nothing has changed, but now the RTD build apparently can't find the conf.py file?
