The plugin makes use of it as it needs to be compatible with older and newer server software. As soon as a future version of PHP will be announced that won’t support it anymore, I will make sure that the plugin will be updated as well. * It looks like your setup might either be incompatible or you have a firewall blocking additional data like the server load from being fetched. * Can you kindly let me know your current server setup? As well as do you have additional plugins installed that might control the heartbeat and your PHP version? Please create and post a link to your`phpinfo();` output * Looking forward to hearing back from you! * Thread Starter [Phuong Tong](https://wordpress.org/support/users/tvphuong41/) * (@tvphuong41) * [3 years ago](https://wordpress.org/support/topic/i-get-php-error-dfehc_max_server_load/#post-16763938) * please help me check. Thank you [https://1ktut.com/info.php](https://1ktut.com/info.php) - This reply was modified 3 years ago by [Phuong Tong](https://wordpress.org/support/users/tvphuong41/). * Plugin Author [Codeloghin](https://wordpress.org/support/users/loghin/) * (@loghin) * [3 years ago](https://wordpress.org/support/topic/i-get-php-error-dfehc_max_server_load/#post-16764079) * Thank you for the additional information: Based on the list of `disable_functions` you provided in [https://1ktut.com/info.php](https://1ktut.com/info.php), it appears that several functions related to system and process execution are disabled or restricted in your PHP configuration. This means that the `sys_getloadavg()` function may be disabled as well, as it falls under system-related functions. * Since you don’t have access to functions like `system`, `passthru`, `shell_exec`, etc., it is likely that you won’t be able to use `sys_getloadavg()` it directly. * If you have access to the PHP configuration file (`php.ini`) or a local `.htaccess` file, you can modify the `disable_functions` directive to remove the functions you want to enable. Locate the `disable_functions` line and update the functions needed. From:disable_functions = system,passthru,shell_exec,escapeshellcmd,dl, show_source,posix_kill,posix_mkfifo,posix_setpgid,posix_setsid,posix_setuid,posix_setgid, posix_seteuid,posix_setegid,posix_unameChange it to: * disable_functions = dl,show_source,posix_mkfifo,posix_setpgid,posix_setsid,posix_setuid, posix_setgid,posix_seteuid,posix_setegid This should resolve your issue. For any other questions feel free to reply to this thread! * Thread Starter [Phuong Tong](https://wordpress.org/support/users/tvphuong41/) * (@tvphuong41) * [3 years ago](https://wordpress.org/support/topic/i-get-php-error-dfehc_max_server_load/#post-16764245) * thanks for your support.

The new plugin version should work for you now even in more restrictive environments. Hope it helps you now!
