The Translate extension can show roughly how complete a translation is in the language bar in five steps. Over the last few days, this has not worked on Meta: plenty of fully translated languages show up as barely started.
@Nikerabbit - I checked in wmf.4 - the translate extension language bar is perfectly working on https://meta.wikimedia.org/wiki/Community_Wishlist_Survey_2019/Banner:
But https://meta.wikimedia.org/wiki/Tech/News/2018/45 still incorrectly displays the completeness of the translation:
I have purged https://meta.wikimedia.org/w/index.php?title=Special:MessageGroupStats&language=fi&group=page-Tech%2FNews%2F2018%2F45 and they are now up to date.
Unfortunately, a trigger is needed to rebuild statistics (such as someone making a translation). I'll consider running a maintenance script to rebuild statistics.
Most pages are now up to date. There are some that are stuck with old values in parser cache, but those will repair themselves over time in the next few weeks as cached entries get expired or manually purged.
Re-checked - the different lang pages show a different progress, e.g.
https://meta.wikimedia.org/wiki/Tech/News/2018/45 will show full green progress for dansk and polski
https://meta.wikimedia.org/wiki/Tech/News/2018/45/zh will not show the progress for dansk and polski
It looks fine to me, so I believe it is parser cache related. https://meta.wikimedia.org/w/index.php?title=Special:MessageGroupStats&language=fi&group=page-Tech%2FNews%2F2018%2F45 looks correct, and it does not involve parser cache.
