Hi I followed the Proftpd/mysql -etch and everything worked fine. Then a few days ago I noticed it had stoppped working. Only thing I can think of doing on the server is apt-get upgrade. Here is proftpd.log Code: Oct 28 13:47:54 sds.dk proftpd sds.dk (18.104.22.168[22.214.171.124]): FTP session opened.

I also tried remove ftpuser and add again but no luck... Any ideas of what is wrong ??
