The APS Catalog has been deprecated and removed from all Plesk Obsidian versions. Applications already installed from the APS Catalog will continue working. However, Plesk will no longer provide support for APS applications.
Please be aware: with the Plesk Obsidian 18.0.78 release, the support for the ngx_pagespeed.so module will be deprecated and removed from the sw-nginx package.

1. Filezilla Server (FTP server tested well with filezilla client)
2. Plesk 9 on Centos5 (working well and accepting backup from other servers except plesk 12)
