ini_set(): A session is active. You cannot change the session module's ini settings at this time
  • I keep getting this error when the admin is logged in, I guess this will be the case when any user is logged in.
    Detailed error message:

    A PHP Error was encountered

    Severity: Warning

    Message: ini_set(): A session is active. You cannot change the session module's ini settings at this time

    Filename: Session/Session.php

    Line Number: 316

    I guess this is a codeigniter bug which suggests adding session_start() before loading the session library $this->load->library('session');

    The cms is using session library at files fuel\modules\fuel\controllers\User.php, Reset.php, Pages.php, Login.php

    I tried adding the below fragment before the session load library

    if (session_status() == PHP_SESSION_NONE) {
    if(session_id() == '') {

    But I keep getting -
    Message:  A session had already been started - ignoring session_start()

    Could you suggest a solution for this?
  • Do you have session_start somewhere else in your codebase?
  • No, I have not used session_start anywhere.. Why is the forum panel not accessible via phone!
  • Hi Admin,

    Any luck here..
  • I'm unfortunately not able to replicate this issue locally. Is this happening to you on a fresh install of FUEL?
  • I don't know, what qualifies for fresh install. Initially on the fresh install there is only one home page. I logged in to admin panel, but I guess there is not much happening on a fresh install, so there is no session related issue.
    The issues started showing up once I have added modules - custom models for data. Then the home page started showing session error that I have mentioned above.
  • Were you able to identify what custom modules seemed to be triggering the error?
  • Hi Admin,

    Extremely sorry for the delayed response, as I had some deployments lined up!

    I tried commenting each one of the modules but still not able to figure out what was causing the session error to popup.

    I tried to work-around the issue by creating a function which check whether the session is already set!

    //custom function to check if the session error is resolved
    function is_session_started()
    if ( php_sapi_name() !== 'cli' ) {
    if ( version_compare(phpversion(), '5.4.0', '>=') ) {
    return session_status() === PHP_SESSION_ACTIVE ? TRUE : FALSE;
    } else {
    return session_id() === '' ? FALSE : TRUE;
    return FALSE;

    I added the above function in
    fuel/codeigniter/libraries/Session/Session.php end of file in the CI_Session class

    Also introduced the check on line 143
    if ( $this->is_session_started() === FALSE ) session_start();

    In the same file at line 316, I resolved or rather suppressed the error
    ini_set(): A session is active. You cannot change the session module's ini settings at this time
    by commenting out line 316
    //ini_set('session.use_trans_sid', 0);

    I am not sure if the above commented line will have any adverse effects! I would like to know if I should go ahead this way. The above mentioned actions sorted the session related issues.

Howdy, Stranger!
