What do you mean by down? White screen or error message?
The URLs would be useful so we could try to view the sites.
Bluehost will not offer advice for anything that is not a server fault ... Useless!
I would be happy to take a look for you but I would need to login to your Bluehost account.
If you do want me to take a look, contact me by Private Message.
When I spoke to Bluehost I was told that the website is php 5.4 and they no longer support it and no one could offer any help
If you want this doing for you as a job, contact me by private message and I will explain better the process I use for recovering your site.
