 ## Bugs
 ### mathjax
-If you are using [hexo-filter-mathjax](https://github.com/next-theme/hexo-filter-mathjax) or any other plugin that uses mathjax to render mathematical formulas locally, you may encounter an `Error: Can't find handler for document` when rendering articles that include code blocks and have mathjax rendering enabled. This is a problem with mathjax, as its LiteDOM cannot parse complex HTML fragments.
