Plugin not work and show

Product Support

AI-generated summary

In a support thread titled ‘Plugin not work and show,’ Bank_Live reports that after installing the discourse-calendar-plugin, the MathJax and whos-online plugins stopped functioning. Despite rebuilding the app multiple times, the issue persisted, with Bank_Live suspecting cache-related problems. cpradio advised checking the browser’s Developer Console (F12) for errors and clarified whether the problematic plugin had been removed. Bank_Live shared screenshots showing a ‘plugin-third-party…’ error and confirmed they tried reinstalling MathJax and whos-online without success. cpradio suggested disabling MathJax temporarily and installing the official Discourse Math Plugin instead. Bank_Live confirmed that removing MathJax restored whos-online functionality but MathJax still failed, with the same error appearing. cpradio requested the full error and asked if the markdown-it setting was enabled. Bank_Live shared their container configuration, confirming the markdown-it setting was enabled, and included screenshots of the error. cpradio identified the issue: Bank_Live had installed the outdated kasperpeulen/discourse-mathjax.git instead of the current discourse/discourse-math.git. After switching to the correct plugin, Bank_Live confirmed the fix worked and thanked cpradio.

I try

cd /var/discourse
git pull
./launcher rebuild app

We need to know what error is being thrown, so after visiting your site, press F12, which should open the Developer Console and copy the error.

Also, it isn’t easy to infer if you took out the discourse-calendar-plugin again and did a rebuild or not.

Fairly certain mathjax is the issue, disable that plugin and see if your install works, then install the new mathjax plugin

We would need to know the entire error to help. When you installed the Discourse Math Plugin, did you enable the markdown-it site setting?

Yes, I enable

You still have the wrong mathjax plugin installed.

Change git clone https://github.com/kasperpeulen/discourse-mathjax.git to

git clone https://github.com/discourse/discourse-math.git
