Done. I'm somewhat amazed that this typo ("con un un livello") could persist for four years in 35 messages.
If you cannot edit translations, make sure that you have completed all of Special:Firststeps.
I guess that's because one doesn't actually read the message in his own language. Indeed, I've never read it in Italian.
These new babels are only in use for a few months, I think since MediaWiki 1.18 in October or something like that. I have this template on my user page on Meta and recognized the mistake in January, when an admin had migrated the new babel extension onto my user page and also onto all the others, but I didn’t know, where I could fix it and didn’t search for it longer, that’s all.
Thanks for fixing. It’s correct on my user page here on translate wiki, but not yet on Meta. I once thought about using the old templates instead again because of that mistake. I hope, it’s getting onto the pages soon.
Same here. The correct version only appears on my translatewiki page, not in other WM projects. I wonder how long it takes...
Thanks! I guess it takes some time until the actual messages display correct on wm projects?
