I have now experienced another issue, which doesnt exist in ie8 , but does in firefox and chrome.
with (and only with) the htaccess enabled, whenever i try to upload a file, using the file upload functionality available when creating a link, the browser pops up another login box, asking for your username and passwd. so i put them in, and it trys for a while, and the browser seems to freeze after that. The file doesnt get uploaded.
However, it works as expected on ie8. disabling the .htaccess protection makes it act as expected as well, but obviosly that cannot be a solution due to security issues.
If anyone can help, it would be very much appreciated.
Thanks
Nick.
