When the beginning of the problem, I first looked at other people's issues, found that the problem is quite common, and the reasons for a variety of. I started to see #1154, I used their method, but found no effect. I uninstalled the kramed plugin and reused the hexo's rendering engine. Later, some people say that the default mathjax cdn has been invalid, I changed a cdn. Anyway, try a lot of ways, but do not know where the problem lies

here is my theme's config.yml

@BarryLiu1995 may be u right, but anyway i think what problem is not in Next theme.
Theme Next - it's just templates and styles with some javascripts engines.
Mathjax - it's third party javascript and not Next maintenance it. And as markdown engine too.
It seems, problem in markdown engine in compilation with mathjax or any third-party plugins, what directly support markdown and/or Hexo. And i really don't know about mathjax and how it work, but u may also try to research in our issues by this link or ask in MathJax | Markdown | NodeJS issues. Next it's just template, u must know and understand it.

@ivan-nginx Ok, I got it. I will try to fix my problem by myself.

@BarryLiu1995 i don't know what this is, but see - it's working:
In _config.yml:

# MathJax Support
mathjax:
  enable: true
  per_page: false
  cdn: //cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-AMS-MML_HTMLorMML

In *.md file:

## MathJax fast test

$$lim_{1\to+\infty}P(|\frac{1}{n}\sum_i^nX_i-\mu|<\epsilon)=1, i=1,...,n$$

@ivan-nginx I change Front-matter like this and it work
