My Magento installation was working fine until recently I started getting the following error when trying to install extensions with Magento Connect:
INVALID POST DATA
I've checked out a couple of forums and they refer to permissions or firewall issues. I have changed much since it was last working apart from install an SSL certificate and install an SEO component through FTP.
I have a dedicated server running cPanel. Other details are:
Magento [url removed, login to view]
CentOS Linux 5.4
Linux [url removed, login to view] on i686
Milestone will only be released on getting Magento Connect to work.

I can Magento Connect working properly or no money. Milestone is very OK. I need FTP access and login/password to Magento "admin" area. I can start right now.
