I get the following error on only one of all the sites on which we have Wordfence installed.
How do I fix it?
The function wfWAFUtils::normalizedTime() in /wp-content/plugins/wordfence/vendor/wordfence/wf-waf/src/lib/utils.php gives the error Uncaught TypeError: Unsupported operand types: int + string
