 * hello moises2016,
 * Sorry to hear that plugin is not working on your site. Can you tell me what WordPress
   version you have, what PHP version?
    I tried to replicate but I could activate
   CoursePress without problem.
 * Can you try delete and then download again plugin and try to activate? Let me
   know how it goes.
 * kind regards,
    Kasia

 * Thank you for using CoursePress. I am going to mark this topic resolved because
   we haven’t heard from you in a while. If this issue was not resolved we can reopen
   it. Thanks again!
