Site fata error

[gribria]

Hey guys, I have an older site from a client that uses X theme. We’re getting this fatal error:

[17-Apr-2025 17:18:36] WARNING: [pool site-stantheoldhardwareman.com] child 519 said into stderr: "NOTICE: PHP message: PHP Fatal error: Cannot redeclare x_attr_class() (previously declared in /www/wp-content/plugins/cornerstone/includes/functions/shim.php:9) in /www/wp-content/themes/x/framework/functions/helpers.php on line 308"

What needs to be done to fix it?

Hello @gribria,

Thank you for the inquiry.

We may need to inspect the site to fully understand the issue. Please make sure that the theme is updated to version 10.6.4, and then provide the login details in the secure note.

Best regards.
