Unexpected keyword error when using liquid-tags mode

[jreiberkyle]

I get the following error when I attempt to render a notebook using the liquid-tags mode:

ERROR: Could not process ./test_coverage.md
  | TypeError: store() got an unexpected keyword argument 'safe'

I don't get this error if I render the same notebook using the markdown mode.

Context

test_coverage.md

My requirements.txt:

pelican==3.7

nbconvert>=4.0  # for pelian-ipynb
ipython>=4.0    # for pelian-ipynb

Liquid-tags is installed by downloading __init__.py, mdx_liquid_tags.py, and liquid_tags.py to plugins/liquid_tags from the liquid_tags directory of the plugins repo.

Setting for (successful) markdown mode

Hmm.. further testing reveals this is a liquid-tags issue even when I try to render a notebook not using pelican-ipynb. Still, it would be great if someone could try this in their environment and let me know if I'm the only one running into this issue.

You can probably fix it by removing the safe keyword from here: https://github.com/danielfrg/pelican-ipynb/blob/a807798842d4219c296823ebcf58ca31302f033b/liquid.py#L45

You can just remove it on your downloaded version of liquid.py.

Maybe a new version of pelican removed that argument.

As mentioned on https://github.com/getpelican/pelican-plugins/issues/1069 markdown 3 removed that safe kwarg so I removed it from here.

Let me know if that fixes it.

That fixed it!
