Cpanel File manager Extract button disable
===

Today i found extraction of zip file seems disabled in cpanel **File Manager**.Yesterday it was working fine and i had extracted one file .I had uploaded a big file of size 472MB.but then uploading got cancelled and From then  I am facing the problem.

What is the reason behind the strange behaviour of cpanel file manager.?

And what is the solution to this problem..?

I really want the extract button enabled because Upload on server using Filezilla is very time consuming..
