error..
There are two solution for this..
1. Downgrade lamp to previous version
or
2. Edit php source file of drupal.
I prefer to choose second solution since I love to learn new thing
I have tried a few php function like preg_replace() and mb_ereg()
After test each function I think mb_ereg() is good solution.
Go to www/drupal/includes/file.inc
open file.inc
Search for
elseif ($depth >= $min_depth && ereg($mask, $file)) Edit above line by elseif ($depth >= $min_depth && mb_ereg($mask, $file)) Save the file...Open..install drupal..this time u will not face that error..
