Not really resolved, I tried activating it on multisite and gave me error “header missing” I then deleted the plugin from server and tried reinstalling from wordpress and got error “cannot install” So I tried uploading the plugin via ftp and installing it, here is the error message I get.

Unpacking the package…
Installing the plugin…
The package could not be installed. No valid plugins were found.
