How to remove your WordPress files and database?
If you want to remove a previously installed WordPress application, that may require some time. In addition to that, especially when people install their applications manually, they forget to delete their databases after the files are completely removed. This is why we’ve added another option that allows you to completely remove your installation.
To do this, go to your Site Tools > WordPress > Install & Manage. Under Manage Installations, select the preferred one and go to the kebab menu > Delete Application. A new pop-up window will show up. To proceed with the deletion, click on Confirm.
