[Solved] Extract Button Grayed Out / Disabled in cPanel File Manager

Описание: Due to case sensitivity, the cPanel File Manager is unable to recognize zip files. So, it disables/grayed out the Extract option. For example, when the extension is written in a capital letter (i.e. abc.ZIP) then you might experience this issue.

The solution is very simple. Just change the case of extension letters to small. Like abc.ZIP to abc.zip
