 * Hi [@d12ilham](https://wordpress.org/support/users/d12ilham/),
 * Thanks for using our plugin.
    It seems to be in conflict with active themes or
   plugins. Please check to deactivate all plugins one by one and also check with
   the default theme. Let me know if the issue still exists.
 * Thanks & Regards
