What’s up with MathJax? The [MathJax plugin announcement here on meta](https://meta.discourse.org/t/mathjax-plugin-supports-math-notation-using-latex/12826) indicates that it’s broken on the latest version of discourse. The edit history indicates that was months ago, though. Is there any way to get it working?

I’ve tried the [standard install](https://meta.discourse.org/t/142537?silent=true). Thus, my app.yml file has the following lines in the hooks section:

```
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - mkdir -p plugins
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/kasperpeulen/discourse-mathjax.git

```

The MathJax plugin appears on my list of plugins but is unselectable, as you can see:

The plugins console says that MathJax is enabled, at least, but it doesn’t seem to be working on my site.

Got it: After clicking on Change Setting → MathJax Plugin, I found the “Enable MathJax plugin” checkbox was not checked.

Sorry for the noise!
