I faced same problem but got the solution. don’t delete your theme or refresh it. Just go to your cpanel and change your PHP from 5.4 to 5.5 and you will get fix.
@zd26 i got a solution for this. when we update some thing our theme sometime not support it. so just go to your cpanel and convert your PHP from 5.4 to 5.5 and everything will get fine automatically.
