EDIT : I fixed this by doing Raven update !
Hello everyone,
I bought Jupiterx’s adventure template, and I have this warning showing up at the top of the main page of my website (I just put the template and I did anything more for the moment)
**Warning** : Declaration of Raven\Modules\Nav_Menu\Classes\Walker_Nav_Menu::walk($elements, $max_depth) should be compatible with Walker::walk($elements, $max_depth, ...$args) in **C:\xampp\htdocs\depot\jc\capcontinents\wp-content\plugins\raven\includes\modules\nav-menu\classes\walker-nav-menu.php** on line **390**
Do you know if I can get rid of it ? We paid for this. I’m running Wordpress 5.3 locally throught a xampp Windows server.
I hope i’ll get some help here and thank you reading me, have a good day
