This is great Plugin and works well, it has few issues for following activities. I tried with Version 2.9
1) It doesn't work when post is trashed/untrashed.
I identified this is due to following line in function
if ( !$this->post_is_for_real( $post_data ) )
2) User Registration:
There is typo mistake in activity list "user_regisiter" instead of "user_register", Inclusion of i after"s" in register
3) User Profile update: This only works for change password, there is no code written in plugin file for other information like name,email etc.
Additionally It shows you updated your information when you update password of other user.
Let me know if I'm doing anything wrong here?
Thanks for such a great plugin.
