Problem with styling (only default style works)

[fergiemcdowall]

Thanks for making this useful plugin!

I am having a problem: everything seems to work with HTML generation, but the HTML is rendered with no styling.

None of the options under "Pick a markdown and code style:" seem to have any effect with the exception of "default" which does apply a basic style.

The .md file is local on my machine. I am using firefox on a macbook (all fully updated).

Any recommendations for fixing or troubleshooting?

Thanks for reporting and sorry for delay in replying. In the “Tools” > “Browser Tools” menu there is a “Browser console” option which may report interesting error messages (shortcut Ctrl+Shift+J in my browser).

I suppose for the record that “all fully updated” at the date of writing means Firefox 111.0.1 and Markdown Viewer 1.8.1.

Hi @Cimbali,

I will try to answer his place.

same issue:                                only default style works.
fresh Firefox version:     120.0
Markdown Viewer:            1.8.1

I followed your instructions and the Browser console gives:

My console looks like this (interestingly, I couldn't use Firefoxe's screenshot extension while the .md file was open- related perhaps?) ->
