Hello everyone, I installed Wordpress based on this tutorial. I can't use One-click installation because my plan isn't enough for it. Everything is good except one thing: On Wordpress interface, I'm not able to connect to my server. It doesn't accept my information which I can use on WinSCP with zero problem.

Also, there are other problems independent from this. I can use WinSCP on Windows, but on OS X, FileZilla doesn't work for me. I can use Putty on Windows, but again on OS X, Terminal doesn't work for me, too. (WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!) (Host key verification failed.)

My final question is about multiple domains. I added two domains to my droplet. I'd like to set up two different websites. Someone suggests installing a cpanel, others suggest using virtual hosts. I tried Vesta for cpanel but after that, I lost connection to my properly working website. (then I destroyed it) I'm worried about virtual hosts because the procedure of using virtual hosts is very similar to manual Wordpress installation that I used, therefore there is a risk to ruin working website while setting up the second.

Thanks.
