This post will demonstrate how to fix the date problem inside wordpress.

The reason for the date problem is the qtranslate plugin

In order to fix the date problem you need to:

  1. Locate the qtranslate folder inside  wordpress plugins folder. It looks like /wp-content/plugins/qtranslate/
  2. Open the qtranslate_core.php file using a text editor.
  3. Find the function qtrans_strftime line 415 and add the following line after the bracket:
    function qtrans_strftime($format, $date, $default = '', $before = '', $after = '') {
    $format = str_replace('%%','%',$format);
  4.  Save the change and you are done.
