From your two languages pages
1. English
http://www.daewooparts.sk/index.php?...ex&language=en
2. Slovak
http://www.daewooparts.sk/index.php?...ex&language=sk
Both show in my Firefox with the Character Encoding of Central European (ISO-8859-2)
And both show in my IE6 with the Encoding of Central European (ISO)
It seems that you have use the same locale code for your two languages.
Please check in your files of the default English Language Pack.
admin/includes/languages/english.php
includes/languages/english.php
Unless you have intended to set to ISO-8859-2, in the default install of english the follow lines should be:
setlocale(LC_TIME, 'en_US.ISO_8859-1');
And in your Slovak Language Pack,
admin/includes/languages/slovak.php
includes/languages/slovak.php
you should check, find and set the correct locale code for your language.
Or may be you should ask your web hosting for the correct code for your locale as they know better for their server setting and languages support.
