 * I have downloaded and uploaded the file from this webpage as well as used the
   Search feature within WordPress 3.9.2 to download and install this plugin successfully,
   only to have it not Activate due to an invalid header?
 * Error: “The plugin does not have a valid header.”

 * I have already tried the solution of making sure the plugin’s php and core files
   are directly inside the one zip file instead of multiple, but to no avail, it
   still shows invalid header.
 * I would love to be able to try this free option out before I purchase the premium
   version of this plugin.
 * Thanks in advance for any assistance with this issue.
