I have tested scripz and found an error:
After login with admin/admin I tried to add new user (member). I entered all required fields and when I press Create, received error that
user was not added.
I examined code of : MysqliDb.php. I found error on line: 928
$this->_query .= ' (`' . implode($tableData, '`, `') . '`)';
Line 928 should be: $this->_query .= ' (`' . implode('`, `', array_keys($tableData)) . '`)';
