We have a new server using Plesk 7.5.3 Reloaded/Fedora2 Whether attempting to install applications through a client's account login or our server admin login, we receive the same errors when trying to install applications to any account/domain. If we create a database beforehand and use that data for the application vault installtion, we receive notice that the database/database username is already there, thus unusable. Is this a configuration problem with our Plesk Installation or is it a bug in the AppVault. We have updated our server both through the Plesk interface and yum updates. Any suggestions, help and/or URI for help files will be greatly appeciated. Thanks to all who are willing to point the way.
