Session loaded multiple times

It is not an error. It's only a bit of info you can use to optimize your code. As the message says, the attempt is ignored and the session is not loaded again.

Even though you cannot find it, there must be a line of code that runs $this->load->library('session');

What piece of code is always executed? Look in those places for redundant load attempt.

HI, i found it an managed to solve this

thanks
