Liquid Exception: exit in _layouts/post.html about minimal-mistakes

[mmistakes]

Check your post and page YAML. It's probably in the wrong format in one of your posts or pages. Needs to be YYYY-MM-DD

Do you have a link to the problem repo?

Do you have a link to the problem repo?

No sorry it's a private repo.

It's probably in the wrong format in one of your posts or pages.

I just double check that it's possible but I think not. I think if there is really a problem with a wrong filename date_to_xmlschema(page.date) should also fail.

[mmistakes]

It's not the filename that's causing the problem, Jekyll would barf on that right away. In one of your post's or page's in the YAML front matter you can also set date: and modified: for the dates that are used in the "published on" line. If the format is wrong there the Liquid filter for converting the date into XML schema will fail.

Look through each of your posts and pages and make sure you're using the correct date format in the YAML front matter.

I just check the date is not set by the YAML header in my case. So it parsed out of the filename:
https://github.com/jekyll/jekyll/blob/a0b30a9cc7200041c000dcbbc5266544fc680306/lib/jekyll/post.rb#L162

[mmistakes]

Without a link to some code or a repo I really can't troubleshoot it further. In my experience the only time I've seen this error was from dates being set in the wrong format. Or maybe you have a Ruby gem that is out of date and needs updating.

This happens to me when I get a new minimal mistakes theme and remove all the existing posts.

Edit: this was happening to me because I moved the existing posts in _posts out of the way and into a top-level subdirectory called "foo". jekyll looked in there and tried to parse the files but the post layout didn't get applied correctly because they weren't in the _posts directory. Moving foo outside of the jekyll site repo fixes this.

@tgamblin I think I had the same problem as you. So I close this for now.

[dalufine]

I have the same problem.then i find that there is a .md file outof the dir _posts,delete it,it's work.(not't case my english)

[nibra]

You can move the posts to an "example" directory without problems. You just have to add "example" to the exclude list in _config.yml.

Thanks everyone! I finally caught the one left .md file which caused the problem!
