[charmed_ones]

I just installed a fresh version of 5.84 and install the summary report and I'm getting an error

I get this then the report is displayed as normal
Anyone seen this before?
The line the system is complaining about is

return $this->number_format(round((($v1 - $v2) / $v2) * 100, 1), 1) . '%';
