Site's main directory doesnt works

[em94mu57]

Hi, Today my site's public_html directory stopped working, http://em94.tk/mh/ http://em94.tk/amail/ and other directories are working, but http://em94.tk not working. Tried changing index.html's chmod, logged to cPanel, File Manager, Root directory for em94.tk , then file manager opened, but it's writing Data error. and not showing folders.
