I have the latest version of this plugin, BuddyPress and WordPress. For some reason, the initial email telling the user they need to be approved never gets sent. The only way I could get it to work is following the guidance given by cwhittl here:
Basically says to comment out lines 939 and 940 in the plugin's functions.php file:
//if ( empty( $plaintext_pass ) ) // return;
I have done that and verified that it works, but is there any other way around this without having to modify the plugin?
