Fatal error: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition navigationhistory of the object you are trying to operate on was loaded _before_ the session was started in /home/www/rossbach-friseure.de/shop/catalog/includes/application_top.php on line 309

 

I do keep getting this Message on one out of two Installations on the same Server. The other one ist running perfectly.

 

Buggy: http://shop.rossbach-friseure.de/catalog/

Running: http://shop.btgo.de/catalog/

 

Any suggestion?

After wresting briefly with this problem, I found the solution. The problem is that in some configurations (at least mine), the navigation history section in "application_top.php" doesn't catch the possibility that the session "navigation" variable is registered and the PHP version running is 4 or above. I'm really not quite sure what caused this huge oversight on the part of the developers (with all due respect).

 

Change the nagivation history chunk of code to read:

 

// navigation history
 if (tep_session_is_registered('navigation')) {
   if (PHP_VERSION < 4) {
     $broken_navigation = $navigation;
     $navigation = new navigationHistory;
     $navigation->unserialize($broken_navigation);
   } else {
	 $navigation = new navigationHistory;
 }
 } else {
   tep_session_register('navigation');
   $navigation = new navigationHistory;
 }
 $navigation->add_current_page();

 

and it should work just fine.
