Hi, I just installed this plugin, and the first scan didn't happen. I hit the scan button several times. Nothing. I checked the JS error console, nothing there. No errors in the servers PHP error log, or in the access error log. I do have wp-admin behind .htaccess, but admin-ajax.php is excepted, and is returning a 200 response code according to the browser's console. Any ideas on what's happening? I even have WP_DEBUG on.
As I was writing this I just checked the debug log, and found this error:
PHP Notice: Undefined variable: err in .../wp-content/plugins/wordfence/lib/wordfenceClass.php on line 879
