If you have a version of this mod that is earlier than 1.0.4, let me know and I will
give you upgrade scripts for your version.

If you are on version 1.0.4 and you made the changes in the first
post at https://www.phpbb.com/customise/db/mod/postnotices_to_groups/support/compatability_with_phpobb_3.0.12-t_113276
and got it working on phpbb3 3.0.12, here are the additional changes to bring your version in line with version
1.0.5 of this mod:

OPEN
install_postnotices.php

FIND
	'1.0.4'	=> array(),

AFTER, ADD
	// Version 1.0.5 (nothing new)
	'1.0.5'	=> array(),

OPEN
includes/functions_posting.php

FIND
function user_notification($mode, $subject, $topic_title, $forum_name, $forum_id, $topic_id, $post_id, $postnotices = '', $author_name = '')

REPLACE WITH
function user_notification($mode, $subject, $topic_title, $forum_name, $forum_id, $topic_id, $post_id, $postnotices, $author_name = '')

OPEN
includes/mcp/mcp_queue.php

FIND
				user_notification('post', $post_data['topic_title'], $post_data['topic_title'], $post_data['forum_name'], $post_data['forum_id'], $post_data['topic_id'], $post_id);

REPLACE WITH
				// start mod postnotices (and end mod too)...added two parameters to user_notification call in next line so that user_notification knows that we are not trying to trigger a postnotices notification and to feed user_notification the right author username
				user_notification('post', $post_data['topic_title'], $post_data['topic_title'], $post_data['forum_name'], $post_data['forum_id'], $post_data['topic_id'], $post_id, 0, $post_data['username']]);

FIND
				user_notification('reply', $post_data['post_subject'], $post_data['topic_title'], $post_data['forum_name'], $post_data['forum_id'], $post_data['topic_id'], $post_id);

REPLACE WITH
				// start mod postnotices (and end mod too)...added two parameters to user_notification call in next line so that user_notification knows that we are not trying to trigger a postnotices notification and to feed user_notification the right author username
				user_notification('reply', $post_data['post_subject'], $post_data['topic_title'], $post_data['forum_name'], $post_data['forum_id'], $post_data['topic_id'], $post_id, 0, $post_data['username']]);
