help - Item added to cart - but disappears when browsing

[Guest]

Hello,

 

I can add an item to a cart - but when I continue browsing for other products, the items in the cart disappear. The site in question is www.mobilitycare.com

 

I have sid killer installed and uninstalled it to see if thats the problem and saw no change.

 

Any ideas?

 

Thanks.

I think you are on the write track with the sid killer. Double check to make sure you have it completely disabled.

 

//================================================================

if ( ($HTTP_GET_VARS['currency']) ) {

  tep_session_register('kill_sid');

  $kill_sid=false;

 }

if (basename($_SERVER['HTTP_REFERER']) == 'allprods.php' ) $kill_sid = true;

if ( ( !tep_session_is_registered('customer_id') ) && ( $cart->count_contents()==0 ) && (!tep_session_is_registered('kill_sid') ) ) $kill_sid = true;

if (basename($PHP_SELF) == FILENAME_LOGIN ) $kill_sid = false;

// To disbale the SID Killer un comment the line below (will make this an admin selection

//$kill_sid = false;

//================================================================  

 

Like this code.

Thanks Steve. Still no go.

 

I copied and pasted the code you provided and tried commeting and uncommeting the $kill_sid=false line. Both methods did not solve the problem.

 

Any ideas? Is this a problem with application_top.php?

 

Thanks for the help.

After adding a product cart I click on the "cart" button - the cart is also empty.

 

Any ideas?

 

Thanks.

If you notice that if you disable cookies your cart works fine. So, the cart isn't reading cookies. Aparently when you installed the sid killer you disable cookies somewhere. It is setting the cookie, but not reading it. Go back through the install of the sid killer and make sure everything is taken out and you don't have a line with a typo in it. There is another way to disable sids for search engines without using Ian's Sid killer. I'll find it and post the thread here.

I removed the sid killer completely and still the same problem.

 

Would it help if I post any files contents here?

 

Thanks again.

[Guest]

I even uploaded the original application_top and html_output and I am still having the problem.

 

Any idea what other files could effect this?

[Guest]

It turned out that the file categories was causing the problem. I have no idea why, though - can anyone see if anything is wrong:
