I'm sorry to hear that you still have concerns over the Softaculous Installation program. The program is simply there to make application installations easier to manage. It has absolutely no access to your data, as it only references version identification which is not done through the database for WordPress. The file responsible for tracking versions in Wordpress is the version.php file in the wp-includes folder. I'm just saying this to provide information on the issue.
If you don't want WordPress tracked, then use the uninstall option in Softaculous to uninstall your WordPress installation. Then manually install WordPress
. Bear in mind that the current versions of WordPress are set to auto-upgrade.
If you want to preserve your current installation, then make a backup of your installation (Wordpress files and the database). Next, uninstall the installation through Softaculous
. After it is uninstalled, install Wordpress manually. When the manual installation is complete, restore your database and copy your Wordpress files over the existing installation. The URL and location should match the previous installation otherwise you would need to edit the wp-config.php file.
This is the easiest and most complete way to remove your Wordpress installation data from Softaculous. If you have any further questions, then please let us know.
