Getting a message about /class-wp-hook.php

Say I have function enqueue_media not found or an invalid function name in /wp-includes/class-wp-hook.php in line 287

$value = call_user_func_array( $the_[‘function’], $args );

Hello :slight_smile:

Welcome to Envato Forums :wave:

Which WordPress theme are you using?

Thanks! but I apologize for not posting on the correct site.
I’m using Melos Pro by Think Up Themes for the site in question.
I have a very particular client, so have been using several different themes.
