I am getting 503 error page due to event espresso core. Kindly help please.
Here below the PHP error log I’ve got.
PHP Notice: session_start(): ps_files_cleanup_dir: opendir(C:\Windows\temp) failed: No such file or directory (2) in C:\DATA\vhosts\wp_asc\wp-content\plugins\event-espresso-core-reg\core\EE_Session.core.php on line 527
The error posted will not cause a 503 error, it’s a PHP notice that states your server is not correctly configured as sessions can not be created because either C:\Windows\temp does not exist (unlikely) or your site does not have access to it (most likely the problem).
However one thing that stands out is that you are using a Windows based server which isn’t supported, I’d highly recommend switching to a LAMP based stack as we can’t provide support for issues on Windows servers.
