If you're a hosting provider and would like to direct your users to one of your own URL's to upgrade to the deluxe version, you can customize the /usr/local/cpanel/3rdparty/wp-toolkit/var/etc/config.ini file.
First, you will need to create the /usr/local/cpanel/3rdparty/wp-toolkit/var/etc/config.ini file. If it does not already exist, you can copy the sample configuration:
# cp -v /usr/local/cpanel/3rdparty/wp-toolkit/var/etc/config.ini.sample /usr/local/cpanel/3rdparty/wp-toolkit/var/etc/config.ini
‘/usr/local/cpanel/3rdparty/wp-toolkit/var/etc/config.ini.sample’ -> ‘/usr/local/cpanel/3rdparty/wp-toolkit/var/etc/config.ini’
There are two configuration values that can be set in this file to control the upgrade URL's, cpanelWptLiteUpsellUrl and whmWptLiteUpsellUrl. You can add these to the bottom of the file to change the URL your customers are directed to:
cpanelWptLiteUpsellUrl = http://$yourdomain.com
whmWptLiteUpsellUrl = http;//$yourdomain.com
Just replace $yourdomain.com with the URL you want to direct your customers.
If you're a cPanel partner, you can within Manage2 under Company Profile -> Sales Options to modify the URL on all your servers.
