Maybe if you post model and controller code, you would get your answer. Nobody here is psychic.

Fatal error: Call to undefined method CI_Hooks::_call_hook() in /home3/assl2005/public_html/1stsecure.ca/system/cms/core/MY_Controller.php on line 131

Sorry, I am not familiar with CMS, here is the message I am getting when uploaded the files.

Do you know why do you upload those files?
There shouldn't be folder CMS in system folder.
Is that pure CodeIgniter or some other application that is built on CI framework?
This is very different bug than one described in OP.
This way I doubt someone can help.
What was with bugs in model themes_m.php?

A MY_Controller goes in ./application/core nothing should go into the ./system folder
