# "Execute" function does not work

 * It looks like the changes made for v1.3.1 of the plugin, affected manual execution
   of cron jobs.
 * do_action_ref_array($params[‘task’], $params[‘args’]);
    Throws an error when 
   $params[‘args’] is not an array. It seems that the args are passed through via
   ajax as a string?
 * Either way, args should be an empty array() if none are specified for that task.
 * Also, I’m not sure if it’s a good idea to pass arguments via ajax. I would think
   about getting them from _get_cron_array() inside the execute_task() function.
   Otherwise you have to be really careful about the serialization/unserealization
   of the args.

 * Hello,
 * I’m using 1.4 and seem to have the same error:
 * When clicking on ‘execute’ on a single-event-job, I get the following error:
 *     ```
       PHP message: PHP Warning:  array_slice() expects parameter 1 to be array, string given in wordpress/wp-includes/plugin.php on line 576
       PHP message: PHP Warning:  call_user_func_array() expects parameter 2 to be array, null given in wordpress/wp-includes/plugin.php on line 576
       ```
   
 * I debugged a little bit, and in wp-includes/plugin.php on line 536 (do_action_ref_array)
   i get the following message by the following code:
 *     ```
       if(is_string($args)) {
       		trigger_error("string:");
       		trigger_error(var_export($args, true));
       	}
   
       PHP message: PHP Notice:  string: in wordpress/wp-includes/plugin.php on line 540
       PHP message: PHP Notice:  'some@mail.tld,mailsubject,' in wordpress/wp-includes/plugin.php on line 541
       ```
   
 * in wp_schedule_single_event the $args are an array all the time. I think the 
   unserialize isn’t working the right way.
 * Can anyone reproduce this?
 * Thanks in advance!

 * This functions appears to be broken again. The error thrown now is…
 *     ```
       Object { action: "acm_execute_task", task: "zc_quiz_do_batch_report_hook", args: "", noonce: "9ddff7af30" }
