 * Hi
 * I’m unable to activate the plugin.
 * I’m getting the following response:
    Plugin could not be activated because it
   triggered a fatal error.
 * Running on wordpress version 3.8.1 with flatsome theme v1.8.7.

 * Hi
 * I have updated my server to use php 5.5.0
 * However, I am still getting the same error message:
 * Plugin could not be activated because it triggered a fatal error.

 * Hi litter
    Have you tried it on any other theme just for testing purpose. I m
   not sure but could be some conflict with your plugin. It’s just an assumption.
   Let me know how it will go.
