Error
{#
I'd like to use ``build.error|urlize`` here, so we can have nice links.
However, this is not possible because we are using `data-bind="text: error"`
which means that Knockout.js will use the `.error` attribute to fill
the content of this tag dynamically.

Problem in your project's configuration. Invalid "build": expected one of (stable, 6.0, 7.0, 4.0, testing, latest, 5.0, 2.0), got uscisii2/readthedocs:2.0.0
