Deprecation notice for strtoupper #138
Description
The following notice appears:
Deprecated: strtoupper(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/html/wp-content/mu-plugins/sqlite-database-integration/wp-includes/sqlite/class-wp-sqlite-token.php on line 221
A null check is not performed for $this->value in the sqlite-database-integration must-use plugin causing a deprecation notice.
The file is /wp-content/mu-plugins/sqlite-database-integration/wp-includes/sqlite/class-wp-sqlite-token.php on line 214
a fix for this could be to introduce another null check
