I tried:

• renaming "main.hml" to "main.html" (it must be a typo)
• installing lightgallery from pip repo (pip install lightgallery) instead of git+https://github.com/g-provost/lightgallery-markdown#egg=lightgallery detailed in a other issue, note that I used "https://" because "git://" didn't work

[Sonosus]

I have the same issue. @g-provost any advice would be much appreciated! TIA
