Installed but not working

I've just installed the last Dolphin version, but many sections are not available (404 error), for example when I try to visit a profile or the Music section.

Any suggestion?

Thanks in advance!

Try reloading the .htaccess file to your installation.  Dolphin requires this file but sometimes it does not copy over on every installation.

I've uploaded again the .htaccessfile but nothing has changed. :(

First check to make sure your Server has "mod_rewrite" module installed and active, then the second check the .htaccess file and make sure there are entries like : This  , then check to ensure your server is setup to read .htaccess files.
