Agregado theme, permission issues?

Hi all,

I’m trying to use the Agregado theme and get this error:`

Warning: mkdir() [function.mkdir]: Permission denied in /home/mediacra/public_html/romil/wp-content/themes/agregado/functions.php on line 656

Warning: chmod() [function.chmod]: No such file or directory in /home/mediacra/public_html/romil/wp-content/themes/agregado/functions.php on line 658

Warning: Cannot modify header information – headers already sent by (output started at /home/mediacra/public_html/romil/wp-content/themes/agregado/functions.php:656) in /home/mediacra/public_html/romil/wp-includes/pluggable.php on line 865`

I do have the right kind of server and permission issues sholdn’t exist, thought I don’t got cURL access. Has it something to do with my core wordpress installation files?

Any pointers to this problem would be appreciated. Thanks.
