Only default language shows up in a multilingual site
In a multilingual site, I have disabled the languages
option in config.php to prevent the users to add or remove languages from the panel. Languages are added manually by adding language files in the /site/languages/
folder.
The problem is, this plugin needs the languages
option in config.php to be set to true. Otherwise, only pages from the default language show up in the sitemap.
I would suggest using another approach to detect multilingual sites, so we don't need to enable the language options in the panel.
