must be a valid callback
-
I’ve been using your plugin for a long time and have been really happy with it.
Just recently it’s started throwing errors and won’t send emails any more.
PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function “wpb_sender_email” not found or invalid function name in /home/XXX/domains/YYYY/public_html/wp-includes/class-wp-hook.php:324
There’s a trace as well but it’s a bit too long to post here.
Hope you can help.
