.Site.IsMultiLingual was deprecated in Hugo v0.124.0 and will be removed in a future release. Use hugo.IsMultilingual instead.

When building a site with mainroad.

After a short search layouts/partials/widgets/languages.html
Line two

{{- if and .Site.IsMultiLingual (gt (len $translations) 0) }}

Have the same issue

you can search layouts/partials/widgets/languages.html
find {{- if and .Site.IsMultiLingual (gt (len $translations) 0) }}
and then try to use hugo.IsMultilingual instead .Site.IsMultiLingual
i.e. {{- if and hugo.IsMultilingual (gt (len $translations) 0) }}
and run hugo on your site root path

What I wanted to write is actually I have more issues. Vimux kindly refuses to change theme "not to break everyone theme". Well, then I switch to other theme which doesn't have this issue and works with latest versions of hugo. Sad, but true.
