Issue with hook and template library

Ok, well your different route is going to take you longer to figure out, which adds to the cost of your project for something that was already done and working. You must have a very understanding employer/client. It's not as straight forward as the admin_controller. If you've tried both ways, then you shouldn't be having this issue and know that standalone classes/functions/helpers don't know anything about CI until you tell it via get_instance(), just like a custom library/helper/etc.
