Title: Warning: session_start(): Cannot send session cache limiter Last modified: August 22, 2016 --- # Warning: session_start(): Cannot send session cache limiter * [businesscloudinc](https://wordpress.org/support/users/businesscloudinc/) * (@businesscloudinc) * [11 years, 2 months ago](https://wordpress.org/support/topic/warning-session_start-cannot-send-session-cache-limiter-1/) * A user received this error when trying to submit the form. What can cause this and how can it be fixed? * Here is the full error message: * Warning: session_start(): Cannot send session cache limiter – headers already sent (output started at /home/belgianb/public_html/wp-content/plugins/wpgform/ wpgform-core.php:1749) in /home/belgianb/public_html/wp-content/themes/Divi/header. php on line 1 * [https://wordpress.org/plugins/wpgform/](https://wordpress.org/plugins/wpgform/) Viewing 9 replies - 1 through 9 (of 9 total) * Plugin Author [Mike Walsh](https://wordpress.org/support/users/mpwalsh8/) * (@mpwalsh8) * [11 years, 2 months ago](https://wordpress.org/support/topic/warning-session_start-cannot-send-session-cache-limiter-1/#post-5904202) * That is an odd error. It comes from a place in the code where an error message is being sent to the output. * `echo '

' . $error_string . '

';` * Without knowing what exactly is in the error string, it is hard to know why you’re getting a headers already sent message. Is this repeatable? * Thread Starter [businesscloudinc](https://wordpress.org/support/users/businesscloudinc/) * (@businesscloudinc) * [11 years, 2 months ago](https://wordpress.org/support/topic/warning-session_start-cannot-send-session-cache-limiter-1/#post-5904214) * I tested it out myself and did not get an error. Is there a way I can see the error string using FTP? * Plugin Author [Mike Walsh](https://wordpress.org/support/users/mpwalsh8/) * (@mpwalsh8) * [11 years, 2 months ago](https://wordpress.org/support/topic/warning-session_start-cannot-send-session-cache-limiter-1/#post-5904230) * Do you have access to your web server’s error log? I know with a couple of my sites, the error log isn’t on by default but I can go to my hosting console and enable logging temporarily. I can then view or download the log through the hosting console. * That is where I would start looking. * Thread Starter [businesscloudinc](https://wordpress.org/support/users/businesscloudinc/) * (@businesscloudinc) * [11 years, 2 months ago](https://wordpress.org/support/topic/warning-session_start-cannot-send-session-cache-limiter-1/#post-5904271) * This is the error string that I found in the error log: * [13-Mar-2015 21:07:59 UTC] PHP Warning: session_start(): Cannot send session cache limiter – headers already sent (output started at /home/belgianb/public_html/ wp-content/plugins/wpgform/wpgform-core.php:1749) in /home/belgianb/public_html/ wp-content/themes/Divi/header.php on line 1 * Thread Starter [businesscloudinc](https://wordpress.org/support/users/businesscloudinc/) * (@businesscloudinc) * [11 years, 2 months ago](https://wordpress.org/support/topic/warning-session_start-cannot-send-session-cache-limiter-1/#post-5904272) * And this is the header.php * * * * > * * * > * * * > * * * > * * * ” /> * <?php wp_title(); ?> * * * * * ” /> * * * * * * * * > *

There is something which is causing the headers to be generated twice. I need to actually see the form on your web site in order to make a better educated guess.
