@Saransh-cpp looks like the preview pre-path doesn't carry over to links in posts.

I also don't know why certain posts don't have the title page environment variable getting picked up. Seems like a Franklin issue (cc @tlienart)?

@darsnack can you point me to a page that has the issue you're talking about? or is it the items that get listed as Post 6 or Post 10? this is not an issue with Franklin but an issue with the function that does the listing of the posts; I'll have a look to see if I can fix it.

Separately, just had a quick look around (maybe this should go in a separate issue btw so we can go through it gradually), there seems to be a few issues with image links e.g. https://fluxml.ai/blogposts/2021-12-1-flux-numfocus/ looks like that's what this PR is about

I am merging this to resolve the asset and docs link issues. I'll open up a discussion specifically for the hfun issue.

Sorry, I should have been more specific. I opened up #151 to track this.

Hmm, I think this is happening because the navbar points to the folders available in the root directory -

fluxml.github.io/_layout/navbar.html

Lines 13 to 28 in be5b604

	<a class="nav-link" href="/getting_started/">Getting Started</a>
	</li>
	<li class="nav-item">
	<a class="nav-link" href="https://fluxml.ai/Flux.jl/" target="_blank">Docs</a>
	</li>
	<li class="nav-item">

	<li class="nav-item">
	<a class="nav-link" href="/gsoc/">GSoC</a>

I'll try to fix this.

Not just the navbar but also image assets which are inserted like /assets/...
