[IAEP] Main page of the wiki is broken

[Marco Pesenti Gritti]

It seem to be caused by:

{{Translations
  | [[Sugar Labs/Welcome to Sugar Labs|english]] | [[Sugar

Labs/Welcome to Sugar Labs/lang-pt_BR|português brasil]] }}

Is this just broken or do we miss an extension or something to make it
work? The changes was made the 31 May and I'm pretty sure it worked
back then.
