 * Hi!
 * I am having problems trying to access to my site. This is the message:
 * Fatal error: Call to undefined function wp_json_encode() in /usr/home/doordresserblog.
   com/web/wp-includes/class.wp-scripts.php on line 186
 * I have downloaded the file class.wp-scripts.php but I don’t really know what 
   I have to do with it.
 * Could you help me please?
 * Thank you!

 * Celia,
 * It’s likely not an issue with that file directly, and you will most definitely
   not want to modify that file. Is there a plugin that you added or other code 
   you modified before getting that error? It could be a couple of different things,
   but if you have more details that would help pin point the issue a little further.
   Thanks.

 * Hi Will,
 * Thanks for your answer.
 * I have not accessed to the site since a long time, so I have not modified anything.
 * The only thing is that we are changing the hosting… Could that be the problem?
 * Thanks again!
