Hello everyone,
To combine ‘multilanguage’ and ‘widget logic’, you can use this rule in ‘widget Logic’ :
strpos($_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"], 'fr_FR')
So the widget is displayed when the current language will be ‘fr_FR’.
‘fr_FR’,’en_GB’,… are the different values of $mltlngg_current_language.
It works for me, good luck!!!
