    Hi! I'm receiving an error when trying to send a message for an instructor from this page /messages/compose/ This is the error: " Warning: call_user_func_array() expects parameter 1 to be a valid callback, function '__return_true ' not found or invalid function name in /wp-includes/class-wp-hook.php on line 288" Would you help me to fix this ASAP. * Notice that I have updated WPLMS and all plugins.

    hi,

    that's not an issue. its just a warning. simply disable the debug mode in the config file.

    Notices /warnings are nothing to worry about. it has nothing to do with the actual functionality. but if you find any fatal error only then you have to worry about it.

    What are PHP Notices?
    PHP notices are the least important. As stated on the official PHP website, you will see PHP notices when:

    the script encountered something that could indicate an error, but could also happen in the normal course of running a script.

    Refer: https://www.ostraining.com/blog/wordpress/warnings/.

    NOTE: THE ABOVE LINES ARE NOT AN ISSUE. THAT IS JUST NOTICE, YOU DO NOT NEED TO WORRY ABOUT IT. EVERYTHING WORKS FINE.

    you could hide these notices, follow this link: https://www.wpbeginner.com/wp-tutorials/how-to-turn-off-php-errors-in-wordpress

    Hi Veronica. The issue is resolved. Debug mode was already disabled "false" but I have added these lines into config file based on the link you provided. ini_set('display_errors','Off'); ini_set('error_reporting', E_ALL ); define('WP_DEBUG', false); define('WP_DEBUG_DISPLAY', false); Kind Regards, Anas

    This is a warning and this should be taken care of . PLease search your wplms-customizer plugin and check if there is any string like this ? : __return_true    present in it?
