Database connection error when saving a person

For everybody who ran into this problem. Do the following:
In the file plugins/rootspersona/php/class-RP-Persona-Manager.php
comment the following lines in the function process_form.
This recreates the issue with the post-title after changing it, but that’s not a big issue. the database is now at least updated correctly.

/*
=====>>>> REMOVED BECAUSE THIS IS INTRODUCING A Error Message.

$title = RP_Dao_Factory::get_rp_persona_dao( $credentials->prefix )
if($isSOR) {
->get_fullname( $indi->id, $indi->batch_id );
$my_post[‘post_title’] = $title;
}
*/

Thanks! I will try and let you know. So far it looks great!
