When I access as an admin I try to clic on the Admins Only block but the links are broken and it says " HTTP 404 Page not Found" and Im not using any other theme just the Professional the CHMOD of the admin folder is 755 and the files inside like user.php, plugins.php ect. are 644 What can I do?

Is it possible that your hosting service uses a predefined "admin" directory (where you can administer your domain)?

If so, you can rename Geeklog's "admin" directory to "myadmin" (or whatever else you prefer) and adjust $_CONF['site_admin_url'] in config.php accordingly.
