Htmlwidgets not displaying on web browsers

[agoutsmedt]

Dear all,

I have written a blog post in .Rmardown , knitted in a .md. I am using HTMLwidgets that I have saved using [widgetframe][https://bhaskarvk.github.io/widgetframe/articles/Using_widgetframe.html] and I am introducing the saved .HTML like this:

<iframe src="/post/exploring-stagflation/index.en_files/figure-html/widgets/widget_DT.html" width="100%" height="500px"> </iframe> 

Everything seems ok and it's working perfectly well locally. However, when after building my website with Netlify, I have a problem with Firefox and Chrome, as they refuse to show the htmlwidgets. You can see the result here: https://aurelien-goutsmedt.com/post/exploring-stagflation/
I am wondering if it can be linked in any way with some features of the academic theme I am unable to track. I have searched a solution for hours and I am really struggling with that... Any help would be really appreciated.

Best,

Aurélien

It appears that apparently the custom header X-Frame-Options: SAMEORIGIN had to be put in netlify.toml and not in config.toml. Problem solved.
My mistake!
