Users cant use explorer 8 and login or add to cart

I recently in the last week started seeing our sales crash and users visiting site and leaving. I finally had a customer tell me website wouldn't let her checkout. I tried and it all worked. Another said the same. I tried again, it worked for me. Then I tried it with explorer and wala... couldn't log in or add product to the cart. Try to add it returns to " your shopping cart is empty ". Try to log in and it just blinks you back to main page? I have the latest version installed 1.3.9h. I have recently added a few scripts like Google checkout and a " Fast and Easy Ajax Checkout " by Numinix . I have disabled both and still nothing. I cant think of anything else I could have changed. I added a new secure cert but I cant find anything wrong with it... again.. EVERYTHING works with Firefox? Please help. Site is copstopshop.com

Thanks,
Joel

What happens if you change your two configure.php files:
/includes/configure.php
/admin/includes/configure.php

to use the www in the URLs?

example:

  define('HTTP_SERVER', 'http://www.copstopshop.com');
  define('HTTPS_SERVER', 'https://www.copstopshop.com');

Problem is that you are using a TemplateMonster template, and you've probably been having this problem since using it. Did you run the 'sql' file that comes with the Template? It would have changed you database in such a way that IE is now having a problem.

Ulitimate solution is to have someone recode the template for you as I'm not sure you can fix the various problems created by TM.

Short term solution is to use one of the following, if Linda's suggestion doesn't work.

Create this file:
IE_disclaimer.htm

Put this code in the file:

<!--[if IE]> <p><strong>Please Note:</strong> We are having issues with the Internet Explorer Browser when trying to Check out.<br />We are working on a solution but in the meantime, please use another Browser such as FireFox or call us at 218-999-9696 and we will assist you with your order and give you 5% off all items for the inconvenience.</p> <![endif]-->

edit this file:
includes/templates/template100003/templates/tpl_product_info_display.php

edit this line:

<?php if ($messageStack->size('product_info') > 0) echo $messageStack->output('product_info'); ?>

to use:

<?php if ($messageStack->size('product_info') > 0) echo $messageStack->output('product_info'); ?> <?php include($template->get_template_dir('',DIR_WS_TEMPLATE, $current_page_base). '/templates/IE_disclaimer.htm'); ?>

That allows the msg. to be displayed at the top of your Product Description pages. Although you have a notice on your Home page, not everyone will come to your site on the Home page and possibly some people will forget about the notice; unless they see it on the Product Description page.

Further checking showed the SSL Certificate used for your site is for: www.copstopshop.com

This means you "must" change the two config files to also use 'www.copstopshop.com' else you will have all kinds of other problems as well.
