An application deployed on a domain can be deleted by Domain User of a given domain and by Plesk Administrator.
If you are a Plesk Administrator, proceed through the following steps:
Note: This page can be accessed via Plesk Desktop. On the navigation pane, click on the Desktop link, then click on the Remove link below the Install a site application button in the Tools section, and get to the Site application installation page where you can choose the required domain in the list.
Plesk will delete the selected application both from Plesk database and from related folders, after which the Installed Applications page will reload and display the list of installed applications without the deleted one.
Note: If the folders associated with the application to be deleted contain files that have been created by the application during its execution, such files and folders cannot be deleted from the domain. The problem is that the delete operation performs with permissions of Domain User, which is not enough to manage the files created with permissions of Apache User. E.g. if an application has been deployed in the application folder within the /httpdocs root folder and there have been any files created by that application during its execution, then such files and the application folder will not be deleted from /httpdocs if one deletes that application from the domain. The side effect is as follows: when one tries to reinstall the same application to /httpdocs again, he will be asked to rename the application folder as the application folder with the default name is present in /httpdocs already.
If you are a Domain User, follow the instructions stated below:
