In the tests of WordPress Manager (alpha version of DA), I noticed the following points:
1. in the choice of the directory, if you choose root (instead of subdirectory), the installation generates an error: Invalid directory: installation directory is not empty
2. I created the installation in a subdirectory, the installation was done successfully, then I deleted the installation, the directory was deleted but not the databases (moreover, the installation creates 03 databases).
