Home page of hugo academic is gone

Hey there. I was updating my website today (no big changes) and at some point the main page stopped rendering. I don't think I changed anything major so I don't know what could I have done.

At first, the blog wasn't rendering at all, but after reinstalling blogdown I get this message:

And the following image for the home page. I can see by the message that there are some issues happening but I don't know how to interpret/fix them. I didn't change anything in the theme folder. Any clue of what's going on?

Hi! Oof. Can you share the version of Hugo (blogdown::hugo_version())? This looks like a mismatch between Hugo versions and your theme. The actual theme should be fixed upstream, so to update it I use blogdown::install_theme(theme = "gcushen/hugo-academic", update_config=FALSE, force = TRUE). But beware- this will overwrite your themes/ folder so hopefully you haven't been editing that one :wink:


Hey @apreshill, thank you for answering. The blogdown version is ‘0.71.0’. I updated the theme as you indicated but I still get the same result. I kind of gave up on fixing it because I think there might be some hidden bugs that will be too fiddly to find, from old problems that I only half fixed. Thank you for your help!

Ok, next idea- check your config.toml file, is this line in there?


Reason: late last year, Hugo switched the default markdown renderer from BlackFriday to goldmark. See https://gohugo.io/news/0.60.0-relnotes/. Goldmark by default calls all raw HTML code unsafe, so you need to configure goldmark to allow raw HTML. I'm not certain this is your issue, but this is what I would check next.
