Config not saved and page edits with errors

Installed your fine mini CWB on our host.
This is not a recomended config being IIS/ windows but it does meet your requirements.

In de admin sedtion the config changes are not saved (no error shown) and when editing/adding a page the error :

Warning: fopen(D:\www\domein.nl\www\cwb\repository/bd.php) [function.fopen]: failed to open stream: Permission denied in D:\www\domein.nl\www\cwb\include\cls_miniFile.php on line 68

As this is a windows host I cannot set file permissions, any way I could resolve this ?

some things just fix them self :) The hoster had a special page to set permissions on windows folders, after setting the ./repository dir writable all worked well.

So now is fixed with this hoster solution??

Yes, that fixed the initial problem.
I ran into 2 more unrecoverable ones:

1) the config is saved, but not used. If I open the config file all the settings are there, but the CMS still is using some defaults it seems. No idea where those come from. On my other windows server I was not able to log in even with the demo/demo standard setup.

2) I had a CGI error trying to open any added or existing page e.g. index.php/test resulted in an error. Php version is 5.2.1 on that server.

1. We save all in tmp/extraconfig.inc.php as well, we actually use this, the config in repository is like a mysql database, just i in text. So chmod to 777 tmp/extraconfig.inc.php

2. It is .htaccess I think. Delete that file and see.
