Just a quick one this evening. A user has recently noticed that the Wordpress plugin called Mingle conflicts with my plugin WP Welcome Email Editor. It, for some reason, causes Wordpress to call it’s own version of the wp_new_user_notification function before my plugin, or any other for that matter, can declare theirs.
The remedy is simple, fix Mingle. In the absence of that you can fix it using the following method:
- Open mingle.php
- After the PHP comment for the plugin at the top add the following code
add_action('init', 'mngl_init'); function mngl_init() { - Right at the bottom of the code before the closing ?>, add the following:
}
- Save the file and then plugins like mine will work with it without causing a conflict.
If either the Mingle author fixes the problem or anyone has a better way of sorting this then please do let me know and I will update this post to let others know.
Please make sure you back up the mingle.php file before making these changes. Just in case 
Please also be aware that if you update the Mingle plugin then you need to put this code in again to maintain the fix.
