Hi,

When I try to run the upgrader from the administration page, it's throwing the following errors:

Warning: touch(): Utime failed: Operation not permitted in /admin/include/pclzip.lib.php on line 3856

Warning: Cannot modify header information - headers already sent by (output started at /admin/include/pclzip.lib.php:3856) in /include/page_header.php on line 101

Notice: Undefined property: Smarty::$ext in /include/smarty/libs/Smarty.class.php on line 671

Fatal error: Call to a member function create() on a non-object in /include/smarty/libs/sysplugins/smarty_internal_templatecompilerbase.php on line 327

any help is appreciated!
