not working when the equation is too long or too complicated

[Sunethan]

I found that MathJax won't work well when the equation is too many "A_{1}^{2}", "\text{1233}" or something like that. For example,

$$\large\sum_{i=1}^n\vec{F}_{\text{ext, i}}=\sum_{i=1}^n$$

This equation won't show LaTeX correctly.

However, if I delete =\sum_{i=1}^n, then everything is fine.

$$\large\sum_{i=1}^n\vec{F}_{\text{ext, i}}$$

I really need your help. I love this plugin so much because it enables me to write a physics blog.
Thank you so much.

This is working for me. Post body:

[mathjax]

$$\large\sum_{i=1}^n\vec{F}_{\text{ext, i}}$$

$$\large\sum_{i=1}^n\vec{F}_{\text{ext, i}}=\sum_{i=1}^n$$

Please provide more details. You state that the longer equation won't "show LaTeX correctly," but don't state in what ways it is shown incorrectly. Do you see no equation? Or the wrong equation? Are there any errors in the console?

Thanks for replying. You can see this image to know the way it's shown incorrectly.

And its MathJax-latex plugin code is this :

Are you seeing any errors in the console?

What are your settings on the MathJax-LaTeX settings page? Mine are:

• inline
• wp-latex checked
• CDN checked
• custom location left empty
• Configuration: Accessible

Sorry for replying late. I'm a little bit busy these days. Thanks for your help ><.

This is my Mathjax setting

Besides, I add some code before in the header.php

<!--MathJax -->	
<script src='https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.2/MathJax.js?config=TeX-MML-AM_CHTML' type='text/javascript'>
    MathJax.Hub.Config({  
     TeX: { equationNumbers: { autoNumber: "AMS" } },  
     tex2jax: {  
      inlineMath: [ ['$','$'], ["\\(","\\)"] ],  
      displayMath: [ ['$$','$$'], ["\\[","\\]"] ],  
      processEscapes: true },  
     'HTML-CSS': { scale: 130 },  
     displayIndent: '2em'  
    });
</script>
<!--End MathJax -->

I'm not sure if the CDN link is correct. It's my friend who help me to add this code. That enables me to use $..$ in inline mode. I've tried to delete this code to see whether everything is well. However, after I delete it and use [mathjax], some mathjax code still doesn't work. By the way, if I use too complicated latex code in inline mode, then something wrong also happens, like $E_{\text{mechanical}}$. it won't show correctly.

Thank you so much.

The error is :

LaTeX Code:
$$\large\sum_{i=1}^n\vec{F}_{\text{ext, i}}=\sum_{i=1}^n$$

It renders like the html code:
$$\large\sum_{i=1}^n\vec{F}<em>{\text{ext, i}}=\sum</em>{i=1}^n$$
