 * Hello,
    I’m ever getting this ‘Update Failed:’ error when I try to update your
   plugin, and I’m ever getting the ‘Installation Failed:’ error whenever I am installing
   your plugin, even on stage sites.
 * What could be the problem??
    What file(s) fails to download / install & causes
   this error??
 * Thanks.

 * I can’t install either and get the following:
 * The plugin does not have a valid header.
