 * I am getting –
 * > Warning: call_user_func_array() [function.call-user-func-array]: First argument
   > is expected to be a valid callback, ‘ngg_test’ was given in /home1/buckman/
   > public_html/wp-includes/plugin.php on line 213
 * Line 213 is $value=
 * > do {
   >  foreach( (array) current($wp_filter[$tag]) as $the_ ) if ( !is_null($
   > the_[‘function’]) ){ $args[1] = $value; $value = call_user_func_array($the_[‘
   > function’], array_slice($args, 1, (int) $the_[‘accepted_args’])); }
 * I would like to continue to use this plugin for a feature we are putting together
   for our member.
