Hi Frantisek,
Our wiki is set as multi lingual with "sk,
en" languages. Default lang is
"sk". Is it possible that this is a problem?
Absolutely, that's the cause of the issue. You need to create a sk
translation of the en page.
To do this, simply go to
.../xwiki/bin/edit/BBCode/Translations?language=sk&editor=wiki , then check
whether the en translations show up in the page and if they do save it. If
the page is empty when you create it, copy/paste the content
from .../xwiki/bin/edit/BBCode/Translations?language=en&editor=wiki to it
before saving.
