If you want to synchronize your license after purchasing one, click on the Refresh License link in your Softaculous Admin Panel. That will syncronize your license information. To synchronize the Scripts / Software, go to the Software Tab in your Softaculous Admin Panel and click on "Update Settings". You will see a log of all scripts being updated.
Softaculous syncronizes with servers for files and License information when CRON is run. You can force CRON to run via some shell commands to imediately sychronize for the License Information or for Script Files. These commands vary from panel to panel so please run the commands as per your Panel.
For cPanel SSH to your server as root and enter following commands /usr/local/cpanel/3rdparty/bin/php /usr/local/cpanel/whostmgr/docroot/cgi/softaculous/cron.php
