I was able to fix the:
PHP Warning: DateTime::modify(): Failed to parse time string (+ second) at position 0 (+): Unexpected character in FOGImageSizeReplace:
$ServiceClass::$zzz != 1 ? '' : 's'with
$ServiceClass::$zzz == 1 ? '' : 's'The same for FOGImageReplicator,FOGImageSize.
FOGPingHosts:
Replace:
$ServiceClass::$zzz != 1 ? '' : 's'with:
sprintf( '+%s second%s', $ServiceClass::$zzz, $ServiceClass::$zzz != 1 ? '' : 's' )
