I used Softaculous to install WP on my main domain. I then have a separate folder, that contains a different website (a forum) with totally different domain.
I would like to install a different script using Softaculous to replace my Wordpress. If I do this, will Softaculous wipe out my forum script thats in the folder that has the completely different domain name and by the way, separate database?
Softaculous did ask what domain I want to install the new script over WP.
If you choose a domain to install a script and points to another path it will unzip the files only on that path and will not overwrite any other files except in that directory.
