The tag katex is not a recognized Liquid tag.

I am creating a basic Jekyll blog. It works flawlessly on local, however on pushing to gh-pages I get the error in the title. Does gh-pages not support this?

Any updates? @cathreya do you have a solution?

GitHub pages limits what kind of extensions you can use. So it is not loading the katex extension, and that's why it isn't recognizing the katex tag. A solution would be to build the site locally and push the _site folder to your repo.
