Want to 301 redirect domain

Hello, I have a website [login to view URL] and I want to 301 permanent redirect the website to xyz.com. I just bought the domain [login to view URL] and We tried though htaccess but it shows the cgi-bin error. Check the attached screenshot for reference error. We are using [login to view URL] between server and website domain so reduce traffic load. The [login to view URL] website has 2 parts. 1) movies 2) documentaries like 1)[login to view URL] has movies and 2) [login to view URL] has documentaries. when we tried to 301 redirect thorough htaccess, the documentary part was perfectly redirecting like [login to view URL] to [login to view URL] but the main movies part does not redirect. It shows attached error. We tried through cPanel webredirects as well but its not working. p.s: the [login to view URL] site has 2 subomains [login to view URL] and [login to view URL] which loads images and other stuff. I want to redirect whole site with subdomains as well redirected to new [login to view URL] domain. Get back to me if you can do this redirection ASAP. Thanks, Austyn
