Today I have observed that all the Header & Footer blocks are missing from Default & Homepage of our theme {Vivashop Energotheme}. Website is displaying only products nothing else.
Attached is the screenshot of Design -> Layout -> Blocks of Default & Homepage.

We have got our hosting server scanned for any file modification in files but didn't find anything out from there. Even we have tried restoring entire website [except Images & var folder] but this also didn't solve the issue.
RCA done from our side.
1. We have not given any FTP access to anyone.
2. Server scanned for modification in files. No such files found.
3. Admin Credentials not shared with anyone.
4. Nothing found in logs about removing blocks.
Please help us retaining our website back and if someone can do RCA on this issue.
