So I have looked everywhere and I couldn't fimd the solution to my problem. I am using steam OpenID, and I keep getting this message: Warning: strpos() [function.strpos]: Offset not contained in string.

```
    if(($host_end = strpos($this->trustRoot, '/', 8)) !== false) {
        $this->trustRoot = substr($this->trustRoot, 0, $host_end);
    }

```
