Hi,
Change the line:
<?php $charsetType = hikashop_get('type.charset'); array_unshift($charsetType->values,JHTML::_('select.option','', JText::_('UNKNOWN'))); echo $charsetType->display('charsetconvert',hikaInput::get()->getString('charsetconvert','')); ?>
to:
<?php $charsetType = hikashop_get('type.charset'); array_unshift($charsetType->values,JHTML::_('select.option','', JText::_('UNKNOWN'))); echo $charsetType->display('charsetconvert',hikaInput::get()->getString('charsetconvert','UTF-8')); ?>
in the file import / file.php for your backend template via the menu Display>Views and it should do it.
