How to Blacklist Scripts

You can use Softaculous to create a list of scripts that you want to remove from your server.

To disable scripts on your server, add the script ids of the scripts you want to disable to the following file in a serialized array format:

For cPanel :

/usr/local/cpanel/whostmgr/docroot/cgi/softaculous/conf/blacklist.ser

For Direct Admin :

/usr/local/directadmin/plugins/softaculous/conf/blacklist.ser

For Plesk, ISPManager, ISPConfig, InterWorx, H-Sphere :

/usr/local/softaculous/conf/blacklist.ser

Note : If the above file does not exist please create the file. 
You can get the Script IDs here :

If you want to disable WordPress on your server, for example, you’ll need to add the following data to blacklist.ser.

a:1:{i:0;i:26;}
