[Plugin: Cart66 Lite] v1.1 – unable to checkout – cart always empty

i having problem with the checkout issue too. When user clicked checkout , it show cart empty. Im using version 1.3.0 .

I have the same problem as well.

I use MAMP in my localhost. I tested using Chrome and Firefox. Firefox works fine. However, Chrome always returns the “Your cart is Empty” message. However, the live site seems to work fine on Chrome.

I want to purchase the pro version. However, I want to wait until this issue solve first.

Been getting clients complaining of the same problem.

I just turned off my WP Super Cache and the EMPTY CART problem seems to have resolved itself on my end.

It always worked on Safari on my end, but my clients could’t make it work on either Chrome or IE. It just worked on Chrome for me after cache shutoff. Clients will try now…

Turns out, it doesn’t work for them. CART EMPTY is the problem they encounter.

Like others have said, these problems do not bode well for Cart66 and the fact that customer support isn’t more responsive makes it even worse.

I have a few e-commerce projects coming up and am unlikely to use Cart66 (not even paid hearing lackluster support there too) for those.

Please help, Cart66 support!

Hey guys. There are a few things that can cause this problem.

1) If you have a caching plugin that has cached the entire checkout page you will get all sorts of funny looking problems as one user sees another user’s cached page. The solution is to disable the caching plugin – at least for the view cart, checkout, and receipt pages.

2) If you site flip flops between different subdomains (like with, then without the www) you can have issues with your session.

3) You need to make sure you have the wp_cart66_sessions table in your database. If you do have it, try to “repair” it from PHPMyAdmin and see if that helps.

The problem we’re having trying to fix this problem is that we can’t reproduce it locally on any of our test systems. We’ve tried our local computers, rackspace, dreamhost, a couple different dedicated servers and just can’t reproduce the problem. But, clearly the problem exists. So, if anyone having this problem is willing to PLEASE let me log into your site I’d love to look into this and solve it once and for all. I’d need your FTP, Database, and WordPress log in info. Obviously we wouldn’t want to do this on a “live” site, but if anyone has a site we can work with that would be GREAT.

Please contact me and specifically mention to pass on the info to Lee (that’s me). I’m sorry this problem exists and I’m focussed on getting this figured out. Thanks guys!

We just released a new version of Cart66 Lite (version 1.4.1) which adds two new changes that may (hopefully) help with the “empty cart” problem.

1) We updated the way the cookie is set using the advice from CammoKing

2) We added the ability to choose whether or not you want to use database backed sessions for Cart66. Database sessions are a bit more efficient and let you do stuff like load balancing more easily so we kept database backed sessions as the “default” session type. But, if it’s not working, you can disable database sessions and Cart66 will use the native, file system based, PHP sessions.

If someone having the “empty cart” problem could please try Cart66 1.4.1 and let me know if it resolves the problem, that would be awesome. Thanks again everyone!

We resolved the issue by turning OFF database caching in W3TotalCache. That’s what was causing the problem.

Test it out, deselect database caching on your caching plugin and see what happens. Chances are it’ll begin working.

I am having the same “empty cart” problem, which occurs in Firefox, Chrome, and IE. I do not have a caching plugin activated, and just upgraded to Cart66 1.4.2. When that didn’t work I disabled the database sessions. Still no help. It appears Cart66 is not creating a WP_Cart66_sessions file. I’ve tried deactivating and reactivating the plugin several times, and have done the same for the rest of my plugins without result. If anyone has another suggestion I would love to hear it.

Hi Gary. Do you have any other plugins installed? If so, if you could try disabling everything other than Cart66 then see if you still have the problem. There could be a conflict of some sort between Cart66 and some other plugin. If that turns out to be the case, please post which plugin has the conflict and we’ll try to get that resolved.

Generally what we do to trouble shoot something like this is to disable all the plugins except Cart66. If that works, then we activate the plugins one at a time, testing after each activation, and when you get the problem again you know that the plugin you just activated caused the problem.

I solved my empty cart problem by turning the “Ajax add to cart” option to YES in the Cart and checkout settings. I’m not sure what the default is, but I had it turned off. Once I turned it on, the add to cart button worked just fine, at least so far. This after I tried every other solution suggested above. I hope this helps someone else with this highly frustrating problem.

Anyone find a fix for this? The ajax add to cart option to yes did not fix the empty cart issue.

I started using Cart66 Lite a week ago on a site and discovered this morning that Internet Explorer 8 was not adding items to the cart. It has been working fine in Firefox and Chrome. I discovered this thread in a Google search. The site is upgraded to version 1.4.3

The site is not using a caching plugin. Running Repair on the wp_cart66_sessions table did not resolve the problem.

When I set Database Sessions to No, items started being correctly added to the cart when using Internet Explorer 8. To double check I turned Database Sessions back on and cleared all domain cookies and session cookies. It reverted to not adding items to the cart. I turned Database Sessions off again and items are again being correctly added to the cart in IE8.

I would prefer to use database sessions. I will monitor this thread to see if you make progress in tracking down the problem.
