Known Bugs (and fixes) with v1.3.8 / v1.3.8a

Problem: Back button not working in some instances and you go to the home page vs the last page

Solution: edit the file
/includes/functions/functions_general.php

around lines 989 - 1004 is the function:

////
// Set back button
  function zen_back_link() {
    if (sizeof($_SESSION['navigation']->path)-2 > 0) {
      $back = sizeof($_SESSION['navigation']->path)-2;
      $link = '<a href="' . zen_href_link($_SESSION['navigation']->path[$back]['page'], zen_array_to_string($_SESSION['navigation']->path[$back]['get'], array('action')), $_SESSION['navigation']->path[$back]['mode']) . '">';
    } else {
      if (isset($_SERVER['HTTP_REFERER']) && strstr(HTTP_SERVER, $_SERVER['HTTP_REFERER'])) {
        $link= $_SERVER['HTTP_REFERER'];
      } else {
        $link = '<a href="' . zen_href_link(FILENAME_DEFAULT) . '">';
      }
      $_SESSION['navigation'] = new navigationHistory;
    }
    return $link;
  } 

replace it with the following:

////
// Set back button
  function zen_back_link() {
    if (sizeof($_SESSION['navigation']->path)-2 > 0) {
      $back = sizeof($_SESSION['navigation']->path)-2;
      $link = '<a href="' . zen_href_link($_SESSION['navigation']->path[$back]['page'], zen_array_to_string($_SESSION['navigation']->path[$back]['get'], array('action')), $_SESSION['navigation']->path[$back]['mode']) . '">';
    } else {
      if (isset($_SERVER['HTTP_REFERER']) && strstr($_SERVER['HTTP_REFERER'], HTTP_SERVER)) {
        $link= '<a href="' . $_SERVER['HTTP_REFERER'].'">';
      } else {
        $link = '<a href="' . zen_href_link(FILENAME_DEFAULT) . '">';
      }
      $_SESSION['navigation'] = new navigationHistory;
    }
    return $link;
  } 

Thanks to Absolute for posting this current solution ...

Note: it has been tested to some degree but not to 100% satisfaction ... granted I cannot break it thus far so perhaps it has ...
