Register Session Error

Hi, I tumbled over an error message caused by the Podigee Plugin.

PHP Warning: session_start(): Session cannot be started after headers have already been sent in /wp-content/plugins/podigee/podigee-quick-publish.php on line 320

So checking headers_sent() turns out that the header was already created and has the following output:

# if(headers_sent()) error_log(json_encode(headers_list()));
["Expires: Wed, 11 Jan 1984 05:00:00 GMT","Cache-Control: no-cache, must-revalidate, max-age=0","Content-type: text\/html; charset=UTF-8"]

If this comes from the wp-core there are only two sources, wp-cron.php:24 and ajax-action.php:184. I’m not sure why wp writs already the header during the init process.

I see tree possible solution,

1. check if the header is already written headers_sent(),
2. on init register_session earlier add_action('init', 'register_session', 9); // default 10
3. or you just start the session if the requested URI doesn’t contain wp-cron.php

Does anybody else has this error?

Regards Valentin
