Cannot send session cache limiter – headers already sent

[mkellam]

Hi,

On March 5th, I started receiving the following error in my error log reffering to wp-affiliate-platform. Can you please advise what might be causing it?

[13-Mar-2014 15:00:05 UTC] PHP Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /home/living/public_html/wp-content/plugins/wp-affiliate-platform/wp_affiliate_platform1.php: in /home/living/public_html/wp-content/plugins/wp-affiliate-platform/wp_affiliate_platform1.php on line 8

After reading through the forums, I first contacted my host to see if there was a PHP issue, but they are telling me all is well with the PHP and they advised me to ask you.

I did notice that this error is consistently generated twice each hour at 4-5 seconds after the top of every hour.

Can you please tell me what it might be? I appreciate your help!

Thanks!

Michael

By the way, I did upgrade WordPress files in mid February but did not change anything in my WordPress or plugins around March 5th. Thanks again!

It is likely you have added another plugin (or added some tweak to your theme) that is trying to add/modify the header after the header is sent from the server. Or your host has changed/upgraded PHP on your server. There is no magic fix for it. Gotta find out what is contributing to this. Try the suggestions in the following post:

OK, thanks! I wonder if there was a PHP upgrade in the background on the server. I’ll check to se if the host has update logs.
