Not sure why the cpu usage display was disabled, but it seems to work fine when re-enabled.
Edit the following…
folder:
/usr/local/www/widgets/widgets/
file:
system_information.widget.php
on or about line #97, change from:
jQuery("#cpuPB").progressbar( { value:false } );
to:
jQuery("#cpuPB").progressbar( { value: } );
save the file and refresh the status dashboard.
