 * Hi, we upgraded our staging server’s PHP to v7.4 and started seeing this deprecation
   warning message:
 * > Deprecated: array_key_exists(): Using array_key_exists() on objects is deprecated.
   > Use isset() or property_exists() instead in /***/***/***/wordpress/wp-content/
   > plugins/wp-rss-aggregator/vendor/twig/twig/src/Template.php on line 595
 * Is there a fix in progress for this or is there something we can do on our end
   to resolve this?
