 * With Campaign Monitor Dashboard 1.1.5, got an error “The plugin does not have
   a valid header.” upon trying to activate on WP 3.91. (My Wp install is in a custom
   directory, but that’s not posed a problem with any other plugins.)

 * Hi Servemark,
 * Thanks for reaching out and I’m sorry you had issues. I have tried to replicate
   your issue but with no luck yet….
 * Is this still proving to an issue and does it still happen in 3.9.2?
 * Keen to hear more and try and fix the issue.
 * Please don’t hesitate to email me with any questions.
 * Regards,
    Jake

 * Tried to install via web on a hosted WP 3.92 site and it worked and activated
   fine. Tried again on my local ready to go 3.92 prototype and it installed but
   failed to activate, giving same error.
 * Hope that might provide a clue. Let me know if you want more info.
