Cómo hago para instalarlo, gracias
There might be several reasons of the issue:
1) The archive was not fully downloaded or it is corrupted.
2) Your server does not have ZIP archiver installed.
Anyway you can install it manually. To do it:
1) Download the plugin again to ow_plugins directory
2) Unpack the archive
3) Go to Admin Panel -> Plugins -> Available Plugins
4) Find Group Cover and press Install button
If you want I can install the plugin for you. I need FTP and Admin access to do it.
