"/ajax.php" adds itself to the navigation history

I tested the initial "dirty workaround" against the same environments I listed above (suPHP is used on the Debian box). Can you share which environment(s) it did not work in (so I can add it to my test environments - if possible)?

And there is my smile for the day! Currently communicating with a hosting provider who managed to get on one of the mx blacklists (and somehow I found out before they did - which is unusual).

We tested several environments, including developer machines and live hosting servers:
Debian/Mac with PHP 5.6
Ubuntu with PHP 5.5
CentOS with PHP 5.3

It started removing the wrong things the more we clicked around and added/removed things, and visited other pages, and logged on and logged off, etc, in various combinations, and then finally would just leave the navigation array completely empty, making the button do nothing.

Thank You!

Time for me to add a CentOS box to my list :)

I changed the line number, the regex pattern, and added a return ... in my updated earlier post: http://www.zen-cart.com/showthread.p...99#post1269499

 if (preg_match('|ajax\.php$|', $_SERVER['SCRIPT_NAME']) && isset($_GET['act']) && $_GET['act'] != '') return; 
global $request_type, $cPath;

And also test on a Windows server too?

Works fine on my local development server:

Linux Mint 17.1

Server OS: Linux 3.16.0-28-generic Database: MySQL 5.5.40-0ubuntu0.14.04.1
Server Date: 14/01/2015 18:46:51 Database Date: 14/01/2015 18:46:51
Server Up Time: Disabled/Unavailable HTTP Server: Apache/2.4.7 (Ubuntu)
PHP Version: 5.5.9-1ubuntu4.5 (Zend: 2.5.0)

Clicked around, back/forward button (Firefox), added to cart, updated cart items, logged out, logged in again, back/forward etc - all without problems....
