Intermittent 404 File not Found

Intermittent 404 File not Found

For the past 2 weeks I have had an intermittent issue where my home page will display a generic 404 File not Found error page.  All other pages are available and my site's domain is properly mapped.  Whenever I call support, they speak to a developer and the issue gets resolved within 2 hours without any real explanation of the root cause for the issue. 

After a day or two, the same issue occurs and the home page is not accessible again.  I will call support and go through the same cycle with the same assurances that the issue is going to be resolved within 2 hours.  Sure enough the issue is temporarily resolved and the next day the issue occurs again.  

This recurring issue has been going on for 2 weeks without a permanent solution.  I am using CloudFlare as my DNS server and Zoho Sites Support has checked all of my settings and confirmed that everything is set correctly.  Zoho Sites has confirmed that they have an issue but they cannot solve this.
