Blocking Access to Updater Functions from the Control Panel Linux Hosting
If you delegate server administration tasks to other users, but do not want them to use the Updates function or change the updating settings from the control panel, you can remove the screens related to Updater settings and the Updates icon from the control panel.
To do this, use the following MySQL command:
echo ‘REPLACE misc SET param=”disable_updater”, val=”true”‘ | mysql psa -uadmin -p`cat /etc/psa/.psa.shadow`
To restore the Updates icon and screens in the control panel, use the following MySQL command:
echo ‘REPLACE misc SET param=”disable_updater”, val=”false”‘ | mysql psa -uadmin -p`cat /etc/psa/.psa.shadow`
