Hello,
I deactivated all plugins, except GP Premium, and enabled Debug.
I get this error on frontend:
Deprecated: stripos(): Passing null to parameter #1 ($haystack) of type string is deprecated in C:\xampp\htdocs\grani\wp-includes\functions.wp-styles.php on line 90
And this error on backend:
null to parameter #1 ($string) of type string is deprecated in C:\xampp\htdocs\grani\wp-includes\formatting.php on line 2772
Active theme is GeneratePress Child (the one available on your website).
WP version is 6.0.1. PHP Version: 8.1.6
Thank you
