Thanks a lot, this indeed seems to have been the root of all problems. Wikimetrics now works like a charm, not a single error this time. On a wider note, many American-designed pieces of software have a problem with non-Latin 1 characters (for instance both Picasa and Content Translation had Alt+s shortcut reserved for saving, whereas it’s the only way most of us write ą, one of the letters of the Polish alphabet). I wouldn’t have guessed that the problem here might be with the very existence of non-Latin 1 signs anywhere in the data. Thanks for spotting it – and for your assistance.
Cheers

Subject: Re: [Wikimetrics] How to report a problem?

Halibutt,

I could finally find out what the problem was (or at least *one* problem was).

You uploaded some cohorts with special characters in their description:
"Wikiwarsztaty dla Małopolskiego Instytutu Kultury, Kraków, kwiecień 2015",
which should be completely fine.

However, it seems Wikimetrics crashes if this happens! So it *is* a bug.
Sorry for that!

I filed a task in Phabricator, our bug tracking system:
https://phabricator.wikimedia.org/T100781
We'll fix this in short.

I also removed the descriptions of your cohorts, so you can continue to use Wikimetrics, until we fix the issue. Please, let me know if this indeed solved your problems.

Cheers!
