Broken theme demo links

I’m new to Zola and found a few broken links for some of the theme demos. Where is the best place to report the broken links?

Also if the correction seems obvious for some of them (like the link in the GitHub page for the theme that is sometimes different and works), can/should I try to update the link instead?

Some of them are broken because of issues with the current docs generation. I need to disable all header anchors to avoid them.

Would a list of the broken ones I found be helpful? Or not really because, they will automatically get fixed once the issue with docs generations is resolved?

PS. Already created the spreadsheet with the broken ones from when I went through it.

It should be automatically fixed
