 Hello, I have just installed ubercart on my site, it's great. But when I try to test if it works, it shows a message below: "There are no products in your shopping cart". I try on the ubercart.org site with "Livetest", it show the same message. Would somebody can explaine me what is happen? Thanks for your help. Wang   
Re: "There are no products in your shopping cart.,". Why?
That's what happens if you have cookies disabled in your browser.
Re: Re: "There are no products in your shopping cart.,". Why?
Thanks TR. I understand now.
Re: Re: "There are no products in your shopping cart.,". Why?
I have just checked my browser, the cookie is accepted. But my ubercart still shows the message :"There are no products in your shopping cart." when I checkout. I don't know why. Please help me to resolve the problem. Thanks.  
Try a different browser.
Perhaps it is browser related. It is odd that it happens for you in both livetest and your own site. Try other Ubercart installations from the Live Sites list and see if you have the same issue. If so, then try it from a different browser on a different machine on a different network connection if possible. If it works on the different browser, it is probably a compatibility issue. Either way, please tell us what version of what browser you are using.
Re: Try a different browser.
Drupal works just fine, it's only Ubercart? Are you logged in, or adding to cart as an anonymous user? Do you have anonymous checkout enabled? If you post the URL of the site you are setting up we can test it from here and see if it works for us.
Re: Re: Try a different browser.
Maybe he's just really not adding any products to the cart. Could it be a proxy issue or something else that keeps you from having a consistent session ID at the server?  
Re: Re: Re: Try a different browser.
We just had a customer email us with having the same issue. Trying to get more information out of them. 
Got a same problem
hi mate, have you resolved this issue?
Re: Got a same problem
I have seen this when I was trying to hack my dev environment to use an SSL cert that was on a test machine. Going directly through the dev domain name worked, but when I tried to tunnel from the test machine to the dev machine, the session cookie wouldn't stick. I hope that helps someone.
Re: Re: Got a same problem
I was having the same issue on my site, but was baffled for a bit because the problem seemed intermittent. Half the time I would go to checkout everything would be fine, the other half: "no products in your shopping cart". Finally I solved the problem: I was using the cart links module to add products to the cart, so my solution was to have the add link explicitly specify no 'www'. in the URL. This way, when they were redirected to the cart form, it went from http://mydomain.com/cart to https://mydomain.com/cart/checkout without a hiccup.
sites/default/settings.php to the rescue
Another option, Justin, edit your sites/default/settings.php Around 150 lines down the file should be a section about Drupal's unique session cookies. Uncomment the code that looks like this: <?phpand edit it to this: <?phpThis should solve all your woes regardless of which address is used to access your site. Jeff

Re: sites/default/settings.php to the rescue
I've been tracking this bug forever and finally stumbled across this post. I'm using Secure Pages in my clients site and have been getting reports of this happening periodically for the past few weeks, "no products in cart". I could never reproduce it until this morning and finally realized that Secure Pages was the problem. Actually it's not a "problem" because it does exactly what it is supposed to do. Anyway, just wanted to offer another solution to this other than the settings.php one. I used rewrite rules in my .htaccess file to force everything to go to the www instead of the non-www URL. Use the following. RewriteCond %{HTTP_HOST} ^YOUR-SITE\.com$ [NC]Hope this helps someone. Tim
Re: Re: sites/default/settings.php to the rescue
Yah you have to do that other wise when the url changes from www.yoursite.com to https://yoursite.com it'll empty your cart.
Re: "There are no products in your shopping cart.,". Why?
Make sure that you have user with uid = 0

user with userid = 0 solved the problem for me. http://www.ubercart.org/forum/support/8535/products_disappear_cart_when_...

worked for me
Added uid 0 to the DB. Lifesaver! Wonder why uid 0 was missing? Thanks NecroHill!
Re: worked for me
uid 0 is required for anonymous users, as all the anonymous users have a UID 0 . in case UID 0 is not present , add it using insert query.
Re: Re: worked for me
I saw that happen once, long ago during one of my first Drupal installs. I think it had to do with trying to re-import the database or something - for some reason it didn't like inserting NULL values (or possibly values of 0 due to some weird MySQL condition). It's not entirely uncommon.  
Re: Re: Re: worked for me
There's a setting for MySQL to use the autoincrement value when you insert a 0 into a column. I'm not sure if it's a good idea or not for normal Drupal use, but it certainly causes problems when importing the users table.
MySQL dump
Regards user imports and the 0 uid, use MySQL dump to create a sql file for your DB, then feed that file into your new db. I've known about that (0) => next autoincrement issue for a while, but when doing a full dump and restore, all that juice is turned off. this is the ssh command line I use: mysqldump --add-drop-table --allow-keywords --quote-names -v -hhost -uuser -ppass database > dump-08-11-2009.sqlObviously replace host, user, pass and database with your details. To install in a new database use: mysql -v -hhost -uuser -ppass database < dump-08-11-2008.sqlNever failed for me. Good luck 
Same problem, but fixed
Hi Guys, I've had the same problem with the empty shopping cart for anonymous users. A quick check of the users table revealed that my anonymous user had a uid of 3. Changed it to 0 and the shopping cart worked fine. Ubercart is an *awesome* bit of software - many thanks to the developers
UID 0
I'm having this same problem of intermittent drops of items in cart on checkout for anon users. Not sure it's SSL related as mentioned above, but am looking at at UID 0. I'm not an expert at all this. But I look at the UID 0 in the database and there is no name associated with it. It's blank. Is that what it's supposed to be? Is it supposed to say "anonymous" or "anon" or "anonymous user" is it supposed to be blank. Quint
No, that's correct.
You
No, that's correct. You might also look at my issue here: http://drupal.org/node/679422
Just thought I would share my stupidity :-)
Take a look at the code I "lifted" (to make the quantity field in the cart "read only") without paying enough attention (this goes in hook_form_alter): <?phpIf you stole the same piece of code as me, you will notice setting the disabled attribute is a bad idea. Moral: If you want to be able to checkout, use readonly (or maybe someone here has an even better suggestion).
Re: "There are no products in your shopping cart.,". Why?
I am also having this problem with anonymous users getting "There are no products in your shopping cart.". Where do i find the file i need to edit the user id and change it to 0? 
Same problem fixed for me
I just wanted to say the problem was fixed for me when changing the UID of the default user to 0 (it was 3). And I really wanted to say THANKS to the guys developing this module and that I will donate via PayPal once I make some money on the store I'm setting up!
Tried the UID thing
I have read a bunch of forums on how to correct my inability to add items to my cart... check out: http://ripleystuff.com/vt/monogram/products You can then select one of the hats... choose add to cart and it shows up with the no items in your cart! I have looked into the UID=0 but that looks fine. I have unchecked my boost module I installed. If I am logged in as an administrator then it works fine. I also have anonymous users can checkout checked too! My client is not very happy with me so any assistance would be much appreciated! Thanks, Robert
Re: Tried the UID thing
Have you cleared your cache after disabling the boost module? I had this issue on a new install but that was years ago with UC1. Which UC version are you using? Secure Pages modules installed? Any error messages in Drupal or in Apache logs?
Re: Tried the UID thing
I have cleared my cache... I have not, however, not installed Secure Pages because I process payments through Paypal. Ubercart 6.x-2.7 I checked my logs but did not see any errors. I have attached one of my error logs though just to make sure I have not overlooked something.
Re: Re: Tried the UID thing
do you have anything in the drupal logs? admin/reports/dblog
Re: Re: Re: Tried the UID thing
Thank you end user for your persistence. I have attached the most recent page of errors in my drupal log.
