Hello.
Can't run the demo examples of the error encountered:
Fatal error: Class 'PHPExcel_Worksheet_Protection' not found in /var/www/tbki/www/assets/libs/Classes/PHPExcel/Worksheet.php on line 362
It occurs when the execution of a line
$objPHPExcel = new PHPExcel();
in the '01simple.php' file and others
I don't know what to do...
Thanks
