100%CPU probleme with my wordpress website

In that case, I need to ask you why you’re using EC2 rather than a shared or managed WP host. EC2 is a “roll your own” environment that requires understanding a lot of moving parts (and makes support folks mix their metaphors).

I got this in ssh : `[Tue Jun 01 15:21:17.378827 2021] [proxy_fcgi:error] [pid 4272:tid 139856399292160] [client 80.214.157.155: 20971] AH01071: Got error ‘PHP message: PHP Warning: call_user_func_array() expects parameter 1 to be a va lid callback, function ‘chld_thm_cfg_locale_css’ not found or invalid function name in /opt/bitnami/wordpre ss/wp-includes/class-wp-hook.php on line 294′, referer: https://tradingacademie.fr/inscription-FS/

What version of PHP are you using?

Update: never mind. You’re using 7.4 and that’s OK.

PHP 7.4.19

Are you using any security plugins to restrict brute force attacks on your /wp-admin/ ?
(You can check httpd’s access.log if you have bots trying to log in)

Brute force attacks can often consume as much CPU power as the server can provide

Yes im using Ithemes Security, but ive try to desactivate it and looks same problem.

Can you help me with the command for do (You can check httpd’s access.log if you have bots trying to log in) please ??

Are you using the plugin “child theme configurator”?

yes, I have do with the AWS support a restart of apache and thats make the cpu down to 10% its perfect for the moment

That error seems to be coming from that plugin, so you may want to ask their support about it.

And, of course, when all else fails, reboot. ??

Okay, so thank you both for your time I appreciate ! Have a good end day ??
