Aptana FTP "Opening file for write failed"

I normally use aptana to theme my PHP sites.

Ever since I first started using it, at random moments (specially when in a hurry) I used to get the following error: "Opening file for write failed" when I was trying to remotely save a file.

After a quick search around the net it seems like this problem has been described for a few different reasons, starting with ftp usernames containing @ or windows firewall.

Most sites just encouraged people to disable windows firewall, action I don't recommend.

The problem I found was that aptana didn't configure the firewall rules properly.

To do so I just allowed aptana as an exception both in private and public networks and this seems to have fixed the problem so far.

Hope it helps!
