I am trying to update data in the database using PHP prepared statements, but there is an error that I cannot resolve. This error appears in the first line of the code and the error message isWarning: mysqli::prepare(): Couldn't fetch mysqli in C:wamp64wwwnewjornalentryedit.php on line 266 and the line 266 is $stmt = $con->prepare("UPDATE jentress_erp SET date=?, description=?, position=?WHERE token_serial =? AND company=?");: Prepare failed. I couldn’t solve it despite making many changes and modifications to the code, and all attempts have failed. Please review the code and correct it , All variables in the query statement are correct, defined, and have values, and all column names in the query statement actually exist in the jentress_erp table. The connection to the database is also working well in the page.

php code:

$stmt = $con->prepare("UPDATE jentress_erp
           SET  date=?, description=?, position=?
           WHERE token_serial =? AND company=?");
     $stmt->bind_param("sssss", $test_date, $descrip, $_path, $get_data, $company);
     $stmt->execute();
     $stmt->close();
