One of the steps during a Joomla 1.5 installation is the FTP configuration. If you wish to use this feature, you should fill the fields as follows:
Enable FTP File system Layer - Yes
FTP User: the FTP account you will be using
FTP Password: the password for the above FTP account
FTP Root Path: /public_html (if your Joomla is in a subdirectory within your web hosting account, you need to specify the path to the subdirectory - i.e. /public_html/subdirectory)
Under Advanced Settings you should type:
FTP Host: yourdomain.com
FTP Port: 21
You should also make sure the PHP version for the Joomla folder is 5.2. More information visit the article how to change the PHP version for your account.
