(Login) issues WP Admin tool

Hi,

I’ve been able to upload the Dutch translation of WordPress to my webspace, hosted by one.com

I’ve run into the following issues the WordPress admin tool.

Typing: http://www.mydomain.com/wp-login.php in the browser window occasionally get’s me directly to login page but I also get quite a few page not found messages.

Submitting username and password leaves the url as: http://www.mydomain.com/wp-login.php with a page not found message (also after refreshing).

The last 2 days I’ve worked around it by typing: http://www.mydomain.com/wp-admin/ to get to the admin screen. This is every time I try to login

Logging out changes the url to: http://www.mydomain.com/wp-login.php?action=logout but the page has so far never been found. Receive the standard page not found message in the browser window.

I also get regular page not found messages after changing items in the option or users section. However the changes were successfully completed.

Finally;-), within the write post/page sections I constantly see a page not found section just below the buttons for saving/publishing the post/page.

Does someone have a suggestion how I can fix these issues (I looked through the troubleshooting doc’s forums but so far haven’t found any similar posts.)

Cheers
