PHP Fatal error: Uncaught Error: Call to undefined function cornerstone

[jamiepen97]

Hi I am having an error on my site. When I click “Customize” it says theres an error. I contacted my hosting and they say I have a theme error, this is what it is saying:

[07-Jan-2023 07:40:00 UTC] PHP Fatal error: Uncaught Error: Call to undefined function cornerstone() in /home/wrciszr/public_html/wp-content/themes/x/framework/legacy/functions/admin/customizer.php:36
Stack trace:

#4 {main} thrown in /home/wrciszr/public_html/wp-content/themes/x/framework/legacy/functions/admin/customizer.php on line 36

I have updated both theme and cornerstone. Not sure which was first though. I have cleared cache too.

I believe I fixed it, I had 2 cornerstone plugins downloaded? An older version was activated, I deactivated and activated the new one!
