Hi, we are no longer using the Pro theme on one of our sites, yet there is an error at the top of the wordpress dash referring to Cornerstone. The theme is installed but disabled. How can we resolve this?
E_DEPRECATED: Return type of Themeco\Cornerstone\Parsy\Token::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /www/site_586/public/wp-content/themes/pro/cornerstone/includes/classes/Parsy/Token.php on line 33.
Thanks!
