I just came across something that I believe to be a bug with the latest version of jekyll, since it was resolved when I downgraded to jekyll -v 3.1.6 from the latest version. I would really appreciate it if you could please look into this. (The detailed explanation follows.)\r\n\r\n## My Reproduction Steps\r\n\r\n**1** I cloned this jekyll template in my local machine: https://github.com/Bloc/portfolio-iro\r\n**2** I ran these 3 commands:\r\n```\r\n$ gem install jekyll\r\n$ gem install jekyll-paginate\r\n$ gem install pygments.rb\r\n``` \r\n**3** I received the following error when I ran `jekyll serve`.\r\n```\r\nConfiguration file: /Users/bloc/code/portfolio-iro/_config.yml\r\njekyll 3.2.0 | Error:  undefined method `downcase' for #<Hash:0x007fb6bcce5b60>\r\n```\r\n**4** I also tried cloning two other jekyll templates. \r\n   https://github.com/Bloc/portfolio-kami/ \r\n   https://github.com/hcbviolet/hcbviolet.github.io\r\n\r\n   I repeated the step 2 & 3 with each, but as I ran `jekyll serve`, the same \"undefined method `downcase` ...\" was the result.\r\n\r\n**5** I uninstalled jekyll, reinstalled it by doing `gem install jekyll -v 3.1.6`. Now with this downgraged version, everything seems to be working.\r\n\r\nThank you again for all your help, and please let me know if you need additional information. \r\n\r\n---\r\n- [x] I believe this to be a bug, not a question about using Jekyll.\r\n- [x] I Updated to the latest Jekyll (or) if on Github Pages to the latest `github-pages`\r\n- [ ] I Read the CONTRIBUTION file at https://jekyllrb.com/docs/contributing/\r\n- [ ] This is a feature request.\r\n\r\n---\r\n\r\n- [x] I am on (or have tested on) ***macOS*** 10+\r\n- [ ] I am on (or have tested on) ***Debian/Ubuntu*** GNU/Linux\r\n- [ ] I am on (or have tested on) ***Fedora*** GNU/Linux\r\n- [ ] I am on (or have tested on) ***Arch*** GNU/Linux\r\n- [ ] I am on (or have tested on) ***Other*** GNU/Linux\r\n- [ ] I am on (or have tested on) ***Windows*** 10+"},"comment":{"url":"https://api.github.com/repos/jekyll/jekyll/issues/comments/243168582","html_url":"https://github.com/jekyll/jekyll/issues/5163#issuecomment-243168582","issue_url":"https://api.github.com/repos/jekyll/jekyll/issues/5163","id":243168582,"user":{"login":"jimniels","id":1316441,"avatar_url":"https://avatars.githubusercontent.com/u/1316441?v=3","gravatar_id":"","url":"https://api.github.com/users/jimniels","html_url":"https://github.com/jimniels","followers_url":"https://api.github.com/users/jimniels/followers","following_url":"https://api.github.com/users/jimniels/following{/other_user}","gists_url":"https://api.github.com/users/jimniels/gists{/gist_id}","starred_url":"https://api.github.com/users/jimniels/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jimniels/subscriptions","organizations_url":"https://api.github.com/users/jimniels/orgs","repos_url":"https://api.github.com/users/jimniels/repos","events_url":"https://api.github.com/users/jimniels/events{/privacy}","received_events_url":"https://api.github.com/users/jimniels/received_events","type":"User","site_admin":false},"created_at":"2016-08-29T16:01:04Z","updated_at":"2016-08-29T16:01:04Z","body":"Confirming that I ran into this same issue once the `github-pages` gem updated to > Jekyll 3.2 and my site wouldn't build on Github. My `_config.yml` file contained a key named `theme` that I had designed to use in my site before the idea of themes officially existed in Jekyll. \r\n\r\nNow that Jekyll officially supports themes, my previously named key `theme` in `_config.yml` is no longer valid and I have to rename it to something else, i.e. `theeme` so it doesn't conflict with the now officially supported (and reserved) key name `theme` in >Jekyll 3.2"}}
