硬盘启动并且站点崩溃后WordPress错误

Question

The hard disk of our web server went full overnight and one of our sites crashed. We increased disk space and now at the top of admin backend, we are seeing this error:

Warning: session_start(): open(/tmp/sess_9mrmtgmqb49bfs661n4pqhagq1, O_RDWR) failed: No such file or directory (2) in /home/prikkabelled/public_html/wp-content/plugins/woocommerce-simply-order-export/classes/class-export-import-tool.php on line 140

Many other plugins are acting weird as well. What do we need to do?

Here is a possible solution: Warning: session_start() [function.session-start]: open(/tmp/sess_e07..42c14904, O_RDWR)

But not sure what they mean by, "then before start_session,".

Please help!

Your server it's looking for the session info of your session cookie. But that's only a warning not a big problem. The problem it's that warning it's breaking your headers because you're showing errors in the HTML. In a production site that should be deactivated.

Check the wp-config.php of your WordPress and set this on that file:

@ini_set('display_errors','Off'); 
define('WP_DEBUG_DISPLAY', false);
