I was getting this error with the php 5.3.1 upgrade & the site would not work

Fatal error: Call to undefined method tNG_fields::tNG_fields() in /home/onlinemo/public_html/includes/tng/tNG_custom.class.php on line 19

On line 19 was this code   parent::tNG_fields($connection);

I replaced it with this code  parent::tNG($connection);

This has to be changed in the following files

includes/tng/

tNG_insert.class.php,
tNG_update.class.php,
tNG_delete.class.php  and
tNG_custom.class.php
