Hoosk - A CMS built in CodeIgniter

hi - I tried to get this to work but can not log in. I was able to run through the setup process and get the default pages and the prompt to login.
I did some testing - its accepting the credentials but it won't show the default admin screen. when I turned on error logging I got these errors:
