Error Mandrill with WP 5.4

Hey,

I just updated WP to 5.4 and I’m having this error :

Whoops\Exception\ErrorException: contextual_help is deprecated since version 3.3.0! Use get_current_screen()->add_help_tab(), get_current_screen()->remove_help_tab() instead. in /Applications/MAMP/htdocs/local.new-do.co.nz/public/pddm/wp-includes/functions.php:5088
Stack trace:

When I disable the plugin, no error… I saw you were using a filter with contextual_help.
Do you know about this error yet ?

Cheers
