HTTP 405 - Resource not allowed

[evb]

After some extracting troubles of the roundcube package, I could run the installer.
Everything did have the status OK, I could send an email via SMTP, connect to my IMAP server and the database (MySQL) was created.

The problem occured after I encode my login and password (create autouser true in the main.inc.php config file)
When clicking on log in, I get a page "HTTP 405 - Resource not allowed"

- I run under Windows 2000, IIS 5.5, PHP 5 and MySql 5
- I did verify the authorisations of the webserver on the roundcube folder (did put even everyone full access for the moment to be sure)
- I did some googling and found several old posts with the same problem, but never a solution

So has somebody a clue where begin to search?

I've found a tracker ticket of 3 years ago : Ticket #1336523
(http://trac.roundcube.net/ticket/1336523)

Apparently this will be corrected in 0.1.5 version?

See http://www.roundcubeforum.net/showthread.php?t=536&highlight=organization

or

replace in each html file (see skins) the action="./ to action="./index.php

IIS5.0 under Windows 2000 has this bug (corrected in iis6)
