I was having a problem with the RSS feed on the new Kirby-based site I’m building . In the feed I’m seeing:

```
<lastBuildDate>
<br/>
<b>Warning</b>
: date() expects parameter 2 to be long, string given in
<b>
/var/www/v2.getkirby.com/site/plugins/feed/template.php
</b>
on line
<b>8</b>
<br/>
</lastBuildDate>

```

I’ve just checked and the same message is appearing in the feed from the official Kirby blog too.

Am I right in thinking the $modified item in line 8 of the template.php is missing something?

```
    <lastBuildDate><?php echo date('r', $modified) ?></lastBuildDate>
```

I’ve just amended the line to:

```
    <lastBuildDate><?php echo date('r', $site->modified()) ?></lastBuildDate>

```

I don’t know if this is correct - it certainly produces a correct-looking output but I’m no coder.

The warning message says, that `$modified`which is the second parameter in the mentioned `date()`method gets a string, but needs long (which is kind of integer). So this should also work …

```auto
<lastBuildDate><?php echo date('r', (int)$modified) ?></lastBuildDate>

```

[Edit] I just saw, that there’s an open issue for that: [https://github.com/getkirby/plugins/issues/21](https://github.com/getkirby/plugins/issues/21)

Thank you - I don’t really know my way round Git, but good to hear it’s known-about.
