isallowed key characters insert database codeigniter

A temporary solution is that I disabled those limitations by turning if off.

DB_driver.php Line Number: 330 CodeIgniter

Got something like this : 

Error Number: 1064

You have an error in your SQL syntax

DB_driver.php Line Number: 330 CodeIgniter

check the manual that corresponds to your MySQL server version for the right syntax to use near '. ... Line Number: 330

blah blah blah

Solution : use  Xampp + CodeIgniter newest version .

Xampp 1.7.7 failed

Xampp 1.8.1 works ok (tested)

CodeIgniter current version 2.1.3
