Fatal error: Uncaught exception 'Exception' in PHPExcel classes

Question

Can any one please let me know, why this following error has been thrown from PHPExcel classes

    Fatal error: Uncaught exception 'Exception' with message 'Could not close zip file
 /var/www/mydomain/myexcel.xlsx.' in /var/www/mydomain/Classes/PHPExcel/Writer
/Excel2007.php:400 Stack trace: #0 /var/www/mydomain/myexcel.php(173):
 PHPExcel_Writer_Excel2007->save('/var/www/mydomain...') #1 {main} 
thrown in /var/www/mydomain/Classes/PHPExcel/Writer/Excel2007.php on line 400

Answer 1

I hope this exception may occur because of the Excel sheet is still in open state. also please check with the permission of the folder in which you write/save/upload the .xlsx file.

Answer 2

My educated guess would be that this is due to the fact that the permissions on the folder you're trying to write to are wrong. If that's the case, either make the folder writable (which, from the looks of it would be a bad idea) - or try to save to a location where the web user has write access to solve the problem.

BTW What version of PHPExcel are you using?
