I'm running the latest version of Ajenti but I don't see any plugins or options for FTP. Where are the FTP settings located?
Here is what appears to have happened: the update renamed my config.json file and installed a new default config.json file.

I renamed my original file back to config.json and copied the installation_id value from the newly config.json file. It appears that everything is OK now.

Any idea as to why the update would disregard my config file? 
I updated the rest of the packages on my VPS manually and now:
- the ajenti.dpkg-new service is gone.
- ajenti status looks correct.
- I get an ERR_SSL_PROTOCOL_ERROR when trying to connect to Ajenti on port 8000 via https.
- I cannot log in to Ajenti on port 8000 via http (I'm promoted for username & password but the login is rejected).

Thanks for the file name :-)

On Ubuntu (12.04.3 LTS) the location is (I'm running python2.7):

/usr/lib/pymodules/python2.7/ajenti/plugins/apache/  (a symlink) 

The symlink points to:


Thanks. Not what I wanted to hear but not a major obstacle. 

Really like Ajenti. Keep up the good work.
