I have this files in my dict folder:
en.ini
cs.ini
FALLBACK is set to CS
When I have browser set to CS I got CS page
When I have browser set to EN I got EN page
When I have browser set to any other language (PL, SK, etc.) I got EN page (but fallback should go to CS)
-----------------------
Worse situation is when I have only:
cs.ini
FALLBACK to CS
When I have browser set to CS I got CS page
When I have any other language I got EMPTY PAGE WITHOUT MESSAGES (no keys translated)
This effectively prevents me from using auto language feature, because Im unable to use EN.INI as this have to be filled with CS translations.
