Home page does not show up but all other pages do

I have this site where the home page does not show up but all others do. There are no problems in terms of error. All I get is sa blank screen with nothing else on it. By the way, there is content on the page. There are no error messages or anything. I also clicked to the site from the search engine and its still does not show up.

I am going to give it a go from another computer but doubt it will show as inner pages are already showing on my own computer. I have already tried from different internt browsers but to no avail.

 

What's the URL ?
Did you made change lately ? in the home page code or .htaccess file for instance ?

 

I am now finding that I am required to add index.html after site.com for the content on the page to show up.

Before, I didn't need to add index.html

How can I revert back to the site showing up without having to add index.html?

 

Put this in .htaccess :

DirectoryIndex index.html
