Sometimes, when opening your site, you may get following. But you're sure your website is not empty
It's very likely that you didn't set proper default document(file) for your website as home page. You can correct it in our control panel, by following:
Login our control penel at http：//yourdomain.com or http://18.104.22.168
Go to My Domains > yourdomain.com > Website Settings
Click tab Default Docs, add a new line and input the file name that you want to set up as home page. And click Save.
NOTE Sequencing of the files makes sense. Uppper files always override the lowers. Put your files on the top to make sure it's default document.
