CodeIgniter + Plesk + FirebirdSQL

Hello CI,

I have few CI applications on my shared hosting server and there are all working fine.

My CI applications are connected to FirebirdSQL database v2.5.X and collect data for importing into MariaDB which is the main database for the CI applications. I was aked from A2 hosting to add interbase support and everything work fine.

Now, I would like to migrate my applications to dedicated server on CentOS 7 + Plesk, and I added firebird 2.5.6 from Repel and activate pdo_firebird in the php.ini file but I get an error when I call database connection like below, I need some advice what to work.

Thanks for the assistance in the advance...

Code:
