when i try to manage the site, i have this message :

This message usually occurs when accessing site builder directly per “http://us.zyro.com/”.
Site builder can be accessed only via hosting control panel by clicking site builder icon inside.”

Try Google Chrome for accessing the site builder it you’ve not already tried.

I’ve refreshed your FTP for you.
