At the moment, APS Installer works like a charm, on Version ISPConfig 3.1.12, Debian 9. But the statement on apsstandard.org site is confusing : https://dev.apsstandard.org/apps/1.2/wordpress.org/WordPress/Plesk/ "APS Package downloads are now available only by contacting the Vendor directly or by accessing the APS Catalog via an enabled Odin Automation or Parallels Plesk platform. If there is no entry in the platform for a listed package in this public APS Catalog, please contact the Vendor directly to obtain a copy of this class of APS packages." At first glance, ISPConfig is not allowed to download directly from APS Catalog. However, the wordpress APS in ispconfig works! In the aps_packages tabel, I see the link https://apscatalog.com/1.2/wordpres...ackager=Plesk&os=undefined&platform=undefined How it works under the hood? Thx!
