I think that is not text text you mentioned in the first post. The one about topics is
{ HAS_UNREAD_AND_NEW, select,
true {
{ UNREAD, plural,
=0 {}
one {There is <a href="{basePath}/unread"># unread</a>}
other {There are <a href="{basePath}/unread"># unread</a>}
}
{ NEW, plural,
=0 {}
one { and <a href="{basePath}/new"># new</a> topic remaining,}
other { and <a href="{basePath}/new"># new</a> topics remaining,}
}
}
false {
{ UNREAD, plural,
=0 {}
one {There is <a href="{basePath}/unread"># unread</a> topic remaining,}
other {There are <a href="{basePath}/unread"># unread</a> topics remaining,}
}
{ NEW, plural,
=0 {}
one {There is <a href="{basePath}/new"># new</a> topic remaining,}
other {There are <a href="{basePath}/new"># new</a> topics remaining,}
}
}
other {}
}
{ HAS_CATEGORY, select,
true { or browse other topics in {categoryLink}}
false { or <a href="{basePath}/latest">view latest topics</a>}
other {}
}
This string uses the ICU Message Format. See Message Format support for localization for translation guidelines.
Both UNREAD and NEW are greater than 0 when HAS_UNREAD_AND_NEW is true
Either UNREAD or NEW is greater than 0 when HAS_UNREAD_AND_NEW is false`
If I understand the comment correctly, the first is needs to be changed to are, because that’s the text for 1 unread and at least 1 new topic. If that is changed you should see “There are 1 unread and 1 new topic remaining,”
While “There is 1 new topic remaining,” and “There is 1 unread topic remaining,” still use “is”.
If I am right, you can fix this on your forum by changing the first is in js.topic.read_more_MF to an are.
Then we can try the same on the one for messages and create a pull request to fix it for all forums.
