Email custom template – error: Parameter 2 to closure
-
Hello.
I made all the instructions contained in: https://codex.buddypress.org/emails/custom-emails/
But at the moment when the function
add_action( 'wp_insert_comment','codex15766_comment_inserted', 99, 2 );is activated, PHP throws error:PHP Warning: Parameter 2 to {closure}() expected to be a reference, value given in /home/…/public_html/wp-includes/plugin.php on line 525
Thx for any tip.
