Magento

I am unable to install any extensions and I can’t even upgrade already installed. I trying to do this by magento connect manager and I get back message:
CONNECT ERROR: Please check for sufficient ftp write file permissions.
But my directory permission is already set up to 777.

it’s really strange because I used to install and upgrade extensions in that way.

Set the following to 777

/path/to/your/magento-install

/path/to/your/magento-install/downloader

/path/to/your/magento-install/downloader/config.ini

/path/to/your/magento-install/downloader/pearlib/config.ini

/path/to/your/magento-install/downloader/pearlib/pear.ini

/path/to/your/magento-install/downloader/pearlib/php
