IsMultiLingual error on build

[hennio]

Building fails at IsMultilingual. My site is not multilingual btw.

Error

I have the same issue. Locally, it builds, but when I deploy with Cloudflare Pages, I see this error.

It could be that the version of hugo you're using to build is too old. I had this same issue, and eventually realised that debian (on my build docker container) is shipping an old version of hugo.

Actually, sorry, that was a mistake. I did update hugo, and thought the issue was fixed, but it is not. My workaround was to fork the repo, remove the offending piece from the menu.html and switch my git submodule to my fork instead. My fork is here if it helps anyone, but be advised it will get out of date as I won't copy any updates from upstream. Hopefully this issue gets fixed and I can kill my fork.

Yeah I got this error also
+1 for the problem

I got the same problem here, but upgrading Hugo to version v0.128.0 solved the issue for me.
hugo.IsMultilingual was added on version v0.124.0, so your version needs to be that or higher. You can check with command hugo version
