Thanks Chouby for your answer.
1. this is where the theme defines the option I'd like to translate:
$thb_field = new THB_TextField('top-bar-text');
$thb_field->setLabel( __('Top bar text', 'thb_text_domain') );
$thb_field->setHelp( __('The text will be displayed inside the header top bar (Note: accepts basic HTML).', 'thb_text_domain') );
$thb_container->addField($thb_field);
$thb_field = new THB_TextField('copyright');
$thb_field->setLabel( __('Copyright text', 'thb_text_domain') );
$thb_field->setHelp( __('The copyright text will be displayed at the bottom of the site (Note: accepts basic HTML).', 'thb_text_domain') );
$thb_container->addField($thb_field);
I tried to create the wpml config xml, but I couldn't make it work. Could be more precise?
2. this should be the code of the custom language switcher
<ul><?php pll_the_languages(array('hide_if_no_translation'=>1)); ?></ul>
where should I insert it?
Thanks
