While installing wordpress 3.5, moderator suggested me to install SSH SFTP plugin (for SSH authentication); and I did the same. No issue so far and I could install 3.5. But now I am unable to install 3.5.1 because SSH SFTP option is not appearing. I checked at plugin admin page and it is not listed there either. Now I tried to install it again by Add-> New plugin but it says "installed" (right top of SSH SFTP Updater Support plugin page).
Any clue or hint? Or can you guide me how to manually uninstall a plugin. I want to give a try re installing SSH SFTP Updater Support plugin
