@another13 brilliant, thanks. I just added your snippet of code before the
return $out;
Around line 112 So now looks like:
$out .= '</div></div>';
$out .= '</div>';
$out .= "<script>
jQuery('a#thumb_".$field['input_id']."').click( function(){
window.mf_field_id = jQuery(this).attr('id');
});
</script>";
return $out;
Have you checked your log files? If this is a memory size problem then adding the following to your .htaccess file may resolve the problem
php_value memory_limit 64M
