home html page not alway loading

http://www.igdid.com/

Our html 'home' is not loading every time.  Sometimes it does, but not from my devices and not for many visitors.  This is causing confusion for everyone.  It is loading the www.igdid.com/forum page as the www.igdid.com page. 

I have synchronized the forum.  I recently made a lot of changes on the page.  That did not help.  Can you help me please. 

Best,
Felicity
