PHP Warning: on comments.php
-
I am using WordPress 5.9.1 in a multisite install, Graphene Theme version 2.8.6, PHP version 8.0.
The following warning error is sometimes generated in the log:
PHP Warning: Attempt to read property "display_name" on bool in /home/*****/***/blog/wp-content/themes/graphene/inc/comments.php on line 232I can see that it is generated if the previous line in comments.php does not get a valid WP User object and instead returns a boolean false.
I suggest that this function graphene_comment_author_link( $user_id ) be updated to return
$author_link = get_comment_author_link();if the line$author = get_userdata( $user_id );returns a boolean false.
