Hi!
I added the pt_BR (Brazilian Portuguese) language through Admin > Settings > I18n Languages (/settings/language), and also changed on the file /usr/share/nginx/atom/apps/qubit/config/settings.yml
the line default_culture: pt_BR
And then executed
sudo php symfony search:populate
sudo systemctl restart php7.4-fpm.service
When the language selected is any of the included languages when AtoM is installed (English, Français, Español, Nederlands or Português), I am able to hide the "Language" button disabling the item "Language menu" on Admin > Settings > Default page elements (/settings/pageElements)
But if I select the new added language "Português do Brasil" (Brazilian Portuguese) (using the "Language" button) and then disable the item "Language menu" on Admin > Settings > Default page elements, the button "Language" won't hide.
I tried with the themes arDominionPlugin and arDominionB5Plugin and got the same results (works with included languages, but not for Brazilian Portuguese).
Has anyone dealt with such issue? Is there any other thing I should do for this configuration to work?
