I pushed an update to my Github Pages site and it fails the build. Locally it builds just fine though.
Repo: https://github.com/valeIT/valeIT.github.io/
The page build failed with the following error:
The value 'nil' was passed to a date-related filter that expects valid dates in
/_layouts/post.htmlor one of its layouts. For more information, see https://help.github.com/articles/page-build-failed-date-is-not-a-valid-datetime/.For information on troubleshooting Jekyll see:
https://help.github.com/articles/troubleshooting-jekyll-builds
I took a look at "/_layouts/post.html", but my knowledge of Liquid is pretty basic and couldn't see anything wrong in it.
