 * Hi [@israillaky](https://wordpress.org/support/users/israillaky/).
 * I assume your server is running Ubuntu or Debian and you have PHP 5 installed?
   Then you need install php5-json package on your server. If you don’t have the
   access to your server, then ask your system admin or hosting to do this.
