Deprecated: trim(): Passing null to parameter #1 ($string) of type string
-
Since my web host migrated my website, I have this error on the frontend: Deprecated: trim(): Passing null to parameter #1 ($string) of type string is deprecated in /data/sites/web/mysite/www/wp-content/plugins/gravity-slider-fields/class-gf-field-slider.php on line 191
I found out this is deprecated since PHP 8.1 (https://stackoverflow.com/questions/71707325/migration-to-php-8-1-how-to-fix-deprecated-passing-null-to-parameter-error-r).
