Simple Mathjax


This wordpress plugin is yet another simple plugin to load the MathJax scripts at the bottom of all of your pages. It uses a very all-inclusive mathjax configuration by default, with $’s and $$’s the default delimeters for in-line and displayed equations.

A preference pane is added to the “Settings” group where you can choose whether to use MathJax version 2 or 3, change the MathJax server location (CDN) and the MathJax configuration settings. (See this page for details on the options available.)
You can also specify a LaTeX “preamble” of newcommands which will be loaded in a hidden element near the top of each page.

Fork this plugin on GitHub.


Nothing unusual here!

For equations that are inline or in separate paragraphs, it worked like a charm. The formatting doesn't show up in editing mode, just on the published page. I didn't use it for anything more complicated, so I'm only giving it 4 stars as things can get a lot more complicated than this, and on that I can't say how it works.

Simple MathJax makes it possible for me to write maths more efficiently than anything else I've ever used online. Smashing.

MathJax 3 support, and the default config makes MathJax ignore the new block editor.


update latest mathjax version, load mathjax in footer instead of header


send default url to new cdn


minor code cleanup, allow mathjax in admin screens


use safe mode (prevents evil scripts) by default


use wp_enqueue_script to allow others to use mathjax as a dependency (christianp). removed disqus compatibility due to reports of it no longer working.


added disqus compatibility. enclosed the preamble in a hidden span to
cover a small space created by mathjax v.2


improved loading of the LaTeX preamble so that it appears just
below the body tag, rather than in the header


initial release
