Jag har precis installerat phpBB, men när jag ska öppna forumet (index.php) får jag fram detta felmeddelande:

<code>
Warning: main(./config.php): failed to open stream: Permission denied in C:\Inetpub\wwwroot\phpbb2\common.php on line 111

Warning: main(): Failed opening './config.php' for inclusion (include_path='.;c:\php4\pear') in C:\Inetpub\wwwroot\phpbb2\common.php on line 111

Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub\wwwroot\phpbb2\common.php:111) in C:\Inetpub\wwwroot\phpbb2\common.php on line 115
</code>

Någon som vet vad som är fel??
