Warning after change php version from 7.4 to 8.2

I get error warning after changing php version from 7.4 to 8.2
X theme and Cornersone are updated to latest version.
How i can fix this?

Warning : Undefined array key 4 in ** public_html/wp-content/plugins/cornerstone/includes/_classes/classic/class-legacy-renderer.php** on line 170

Hi Zvonimir,

Thanks for reaching out.
It seems a warning which can be suppressed by adding the following code in the wp-config.php.

define( 'WP_DEBUG', false );

NOTE: I will inform the development team on this, and they will look into it.

Thanks

It’s already set up like that.

Hi Zvonimir,

That is great. As I said before, I have already informed our development team for further investigation.

Thanks
