Hi,
I would install Mailjet plugin (https://github.com/mailjet/wordpress-mailjet-plugin-apiv3) on my website but on activation, i got an error : Fatal error: Cannot use object of type WP_Mailjet_Options as array in /var/www/vhosts/xxxxxx/httpdocs/wp-content/themes/tvt/option-tree/includes/ot-functions.php on line 30 (xxxx replace hostname)
Do you have an idea to fix it ?
