Blog requires users to enter password/username for anyone to view??

Hi guys, hope someone can help me here…
I have just set up a blog using the latest version of wordpress, hosted by Zymic. When I or anyone else go to the homepage a box pops up asking for authentication of user name and password when viewed in Chrome (IE and Safari show just the framework of the page, no links/pics). I can log in using my zymic details and everything works fine but public viewers obviously cant.
How do I get rid of this authentication stage…I assume it is a zymic problem not a wordpress problem but am not sure.
my site is at https://www.leautoblog.com or https://www.leautoblog.zxq.net

I have tried changing the file permissions of the root folder….no change. I cant see a htpasswd file or a htaccess file to delete anywhere either (I have activated force show hidden files in Filezilla but could be looking in the wrong place??)

Thanks for your time!
Ben
