 * Hello.
    I recently installed wordpress as our fratenity’s CMS for our front page
   and our brother portal. I ma using the network installation and so far so good.
 * However, everytime I try to install a plugin, as soon as I click “network activate”
   immediately after installation, I get the error “The plugin does not have a valid
   header.”
 * This has occured with every plug in I have installed, not just ones that are 
   incompatiable (or so WP thinks)
    Any help is appreciated.
