I believe this bug was first reported in issue #3, fixed by PR #4 and recently reintroduced again by PR #15.
I do not specify any katex configuration options in my _config.yml file, so jekyll-katex/configuration.rb will set JEKYLL_CONFIG to {}. But then it tries to do a double indexing:
JEKYLL_CONFIG['rendering_options']['throw_error']
The first indexing operation will return nil, so the second indexing operation will throw the following error:
vendor/bundle/ruby/2.5.0/gems/jekyll-katex-0.3.1/lib/jekyll-katex/configuration.rb:34:in `global_rendering_options': undefined method `[]' for nil:NilClass (NoMethodError)
Maybe that code could be expressed more robustly by Ruby's Hash#merge operation? I might try and create a PR for this later.
