The site I'm working on has 1200+ users on the site and whenever they log out they get the below error message;

Notice: Undefined property: front in c:\program files\easyphp1-8\www\mambots\system\joomlacache.php on line 125

Warning: Cannot modify header information - headers already sent by (output started at c:\program files\easyphp1-8\www\mambots\system\joomlacache.php:125) in c:\program files\easyphp1-8\www\includes\joomla.php on line 1158

This stays on the screen or about 3 seconds and then continues to the homepage.

I've checked the files listed \mambots\system\joomlacache.php on line 125 and there seems to be no error there, does anyone have any idea what could be causing it?

The actual line of code in the php file is $_SERVER['cache_path']=$mainframe->_path->front; 

Below is how it appears in the file from lines 122 to 128

  if ($type==0)
  {
      $_SERVER['cache_path']=$mainframe->_path->front;
      $mainframe->_path->front = $mosConfig_absolute_path.'/components/com_joomlacache/mainbody.php';
  }

Does anyone know what the problem is and how to fix it? I'm sure it'll be something simple

Thanks

Paul
