 * Hello ! thank you for this great plugin, I’m enjoying. I had a little problem
   today, when a new subscriber is registering it get an error message as below:
 * Error! Security check failed for membership level validation.
    The submitted 
   membership level data does not seem to be authentic. If you are using caching
   please empty the cache data and try again.
 * Ps; the plugin is updated to the last version.
 * Thank you for helping me.
 * cheers

 * Hi, do you have a cache plugin installed? If you do, have you excluded the membership
   pages from being cached?

 * Hi, I’m using WP super cache, how to exclude simple membership from being cached?
   I tested my website and Wp super cache told me that there is no cached files 
   in the server.
    Thank you for help, I really need a solution.
