Homepage on our website of Philantrophy theme has disappeared for over 1 week Please help

we have been working on this since last Monday, but seem no solution. Yesterday I managed to create a new page to duplicate the homepage but only stayed on for second, and it disappeared again. We also upgraded to a bigger memory space for the website, but it seems this is not the case. Can anyone offer solution? thank you.

Have you tried contacting the author about this over here ? They will probably be happy to help you out.
