Hello, I have problem with clean URL. I needed to start up another site in the subdomain. Then I created, loaded in the D6 installation, I installed the web. I solved the first problem. Total URL was such subdomain.example.com/subdom subdomain. It bothered me, of course, but clean URL here went to set up fine. So I had to enable parameter setting in settings.php BASE_URL subdomain.example.com. Good, web already read in the way I wanted subdomain.example.com. Trouble is that I do not allow clean URL. In the root folder www my main site where I normally clean URLs to work on D6. The subdomain anymore. Thanks for answers. I think, that should be in htaccess.
