type string is deprecated

Hi, can you help me with the following message that I see in my admin area?

Deprecated: is_file(): Passing null to parameter #1 ($filename) of type string is deprecated in?/home/u78159p73086/domains/bbqfriends.nl/public_html/wp-content/themes/posterity/advance/class-posterity-framework.php?on line?157

Elementor won’t load anymore.

Is there an update for the Posterity theme that I use?

Regards, Marcel Enjoy the outdoors with BBQfriends.nl
