Hi,
It seems there's a new problem with named refs : several articles are now displaying errors of having the same name for several references with different content. See my description on https://phabricator.wikimedia.org/T117037
It happens with {{#tag:ref| |...}}, when there's a whitespace instead of nothing in the content part. The whitespace seems to be considered as being a content on its own, rather than being considered as empty.
