From EZP Knowledge Base
First of all, congratulations. Truly. We know how tough it is to build your own site, which is why we hired a professional to do ours!
Now once you have your site designed, whether by using Dreamweaver, Frontpage or even Notepad (if you are hardcore!), all you need to do is upload the site to your account on our servers! Some wysiwyg editors allow you to connect to your account directly but we recommend using the wysiwyg editor to simply design your site and then use an FTP program to upload your files to your public_html directory.
If you don't have an FTP program there is a download link in this knowledgebase article to our favourite FTP program.
If you are having problems connecting to your account via FTP, try this knowledgebase article.
If you've uploaded your website and it isn't working, give this knowledgebase article a shot!
As always, you can also submit a support ticket for help.
