pfSense

Not sure how the column was blank in the config but at one point blank must have been assumed to be "col1" and that has since changed. If the widget has, for example, system_information::open the system information widget will disappear. If other widgets such as IPsec suffer the same fate, they are also missing from display and the Available Widgets panel. Fixing the specification to be system_information:col1:open will bring it back, likewise for other widgets.

Granted this particular firewall has been through a lot over changes over the years, but when the problem presented the widget config was:

<sequence>system_information::open,services_status::open,openvpn::open,undefined::close,undefined::close,undefined::close,ipsec::open,traffic_graphs::open,gateways:col2:open,interfaces:col2:open,log:col2:open,interface_statistics:col2:open,thermal_sensors:col2:open,smart_status:col2:open,[object Object]:col2:open</sequence>

Cleaning that up a bit it all worked when I changed it to this:

    <sequence>system_information:col1:open,services_status:col1:open,openvpn:col1:open,ipsec:col1:open,traffic_graphs:col1:open,gateways:col2:open,interfaces:col2:open,log:col2:open,interface_statistics:col2:open,thermal_sensors:col2:open,smart_status:col2:open</sequence>
