title: create_function() using option-tree plugin depreciated
body: <p>I have installed a wordpress theme I bought online. Then followed by option-tree plugin installation which is part of the requirements of the template.</p>
  
  <p>I get an error </p>
  
  <blockquote>
    <p>Deprecated: Function create_function() is deprecated in /home/trans/webapps/ochokitours_com_wp_app/wp-content/plugins/option-tree/includes/ot-functions-admin.php on line 69</p>
  </blockquote>
  
  <p>everytime the page is loading. This is the line:</p>
  
  <pre><code>  add_filter( 'option_page_capability_' . ot_options_id(), create_function( '$caps', "return '$caps';" ), 999 );
  </code></pre>
  
  <p>I expect the template to run smoothly with the plugin, but the error keeps popping up.</p>
