Only the homepage is displaying when logged out

OK Site Status is set to yes.

I notice that when I assign the site start to another page the original start site becomes unavailable and the new start site is display.

The site status is set to yes

I also notice that if I reassign the start page,the newly assigned start page becomes visible and the previous one becomes unavailable

Have you enabled Friendly URLs in the System Settings? Did you rename the ht.access in the site's root to .htaccess?

Friendly URL was enabled. Interestingly every pages displayed when I disabled it. I have renamed the .htaccess file.

I am developing the site in a sub folder http://www.mysite.com/subfolder/ The .htaccess file referred above is in the subfolder. It that correct?

Ok fixed it by change the RewriteBase in .htaccess from

RewriteBase /

to

RewriteBase /subdirectoryname

Thanks for your help Sottwell

That was going to be my next question
