talk voting returns template parsing error

[xrmx]

Hello, visiting https://www.pycon.it/en/talk-voting/ logged in, with italian language but page text is in english returns:

Template Error: Could not parse some characters: conf.voting|start||date:"l, F jS"

{% load conference %} {% current_conference as conf %}

{% if conf.voting %} Cast your vote now! →

{% endif %}

I've double checked the syntax from the django reference and it looks correct though. There's a double pipe char '|' that looks suspicious. UPDATE: looking at the code the error message looks mangled :|

Talk voting ora da 404 ma ieri andava correttamente
