Hi, Ismael,

I only want to replace this title. It bothers me to install a plugin for so little … I would prefer to replace the text directly in the file. But I don’t know which one it is and in which directory it is.
Thank’s for helping me,

Audrey

Hello,

Thanks for your help. I found another code that works on a forum. To be placed in the functions.php file of the child theme :

add_filter('gettext', 'wpm_traduction'); 
add_filter('ngettext', 'wpm_traduction');

function wpm_traduction($texte) { 
$texte = str_ireplace('Produits apparentés', 'Tap your custom text here', $texte); 
return $texte; 
}

It worked :)
Thank’s again and have a good day,
You can close this ticket if you please;
