Missing message?
In Special:LanguageStats for Norwegian (Bokmål) there is a group Donation Interface - Amazon Gateway that is listed as having one untranslated message. However, when I click it there are no untranslated messages, not even optional ones (I had a similar problem with LocalisationUpdate, but there there was an optional message, and translating it brought the number of untranslated messages to zero). Bug?
There were some outdated stats in the stats table. With some help from Niklas I resolved it.
delete from bw_translate_groupstats where tgs_group = 'ext-di-ag' and tgs_total = 2; Query OK, 489 rows affected (0.07 sec)
Thanks, Siebrand!
