Plesk 12 FTP issues

[raematrix]

We are seeing issues in FTP access since we upgraded Plesk from 11.5 to 12.0. Has there been any changes made between the two versions that would cause this? Basically, customers are not able to log into their accounts using their FTP clients. No errors are being logged to the server.

We tried to install vsftpd but we couldn’t get it to start on the server. Is Plesk blocking this?

Server Type: Linux
Server OS: CentOS 6.4

Is anyone else seeing this behavior?

We're still with version 11.5.30 but suddenly experience the same problem with only SOME domains after last minor update. Others on the same server can log in just fine. Permissions are the same for all domains.
Wasted a whole day on this already... Tried /usr/local/psa/bin/repair --restore-vhosts-permissions but no luck.
