Can't connect CodeIgniter to MSSQL server?

Question

CodeIgniter

I'm trying to set up the application so that it works from a poppy, I kind of followed the guide and it seems that everything worked, at least it finds MSSQL in phpinfo.
mssql
MSSQL Support enabled
Active Persistent Links 0
Active Links 0
Library version FreeTDS
But the application does not work and gives an error, I am not very familiar with CodeIgniter myself, I went through the starting tutorial, tried to google, but did not get a clear answer to the current problem.
Here is the error code
