Cart emptied after logging in

Can you give me some steps to reproduce the issue?

Plugin settings?

What type of products?

Caching?

WooCommerce version?

Other WooCommerce plugins?

https://otbdiscs.com/product/anode-r2/

Add variation to cart, go to cart, checkout, login, error message about items in cart and cart emptied.

Caching via wp-rocket
WC 5.6

What’s the exact error message that is displayed?

So it’s a variable product.

How is the plugin configured? A screenshot of the settings works

When I find time to dig into this I want to have all the information necessary to try to reproduce the issue.

Error after logging in on checkout page…
Checkout
Please checkout within 59 Minutes 34 Seconds to guarantee your item does not expire.
There are some issues with the items in your cart. Please go back to the cart page and resolve these issues before checking out.

I will get a screenshot of settings tomorrow morning but nothing special in CSR Settings.

Sorry for the delay on additional details. I was able to narrow it down to a conflict wtith Redis Object Cache plugin.

With Redis and Redis Object Cache plugin enabled
1) add product to cart
2) login on checkout page
3) checkout page shows “There are some issues with the items in your cart. Please go back to the cart page and resolve these issues before checking out.”
4) cart page shows “Sorry, “product title” is not in stock. Please edit your cart and try again. We apologize for any inconvenience caused.

I also notice that if I now log out and log back in, the items are in the cart and I can checkout.

I tried flushing Redis cache and uninstalling/reinstalling Redis Plugin. No luck.

Thanks for your help!

Thanks for the followup and the steps to reproduce. When I have time to work on the plugin I’ll dig into this issue.

Thank you!

Oddly, I tried to exclude the CSR cache group name from Redis and it is still behaving the same way with Redis turned on.

It’s a complicated issue that I’ll need to reproduce the issue, look at the sessions table, and attach a debugger to some various spots. I haven’t had any available free time yet to get into it.

I did some additional testing on this in dev with only woo, csr and redis.
1) simple products seem to work fine with CSR, Redis and user logging in during checkout
2) variations with only a handful of attributes work fine
3) variations with 6+ attributes have a cart problem when user logs in.
Checkout page error: There are some issues with the items in your cart. Please go back to the cart page and resolve these issues before checking out.
Cart page error: Sorry, “Product Name” is not in stock. Please edit your cart and try again. We apologize for any inconvenience caused.
4) users who are logged in before adding products to cart are fine
5) everything works fine with redis disabled

So it seems that it is related to 6+ attributes on variable products.

Hope that helps.

Thanks, that looks like some good data. I’ve got a bit of free time coming up so I’ll get into it soon.

Do you have any other WooCommerce plugins active that do anything with variations?

I disabled all other plugins before that troubleshooting. Just had CSR, Woocommerce and Redis Object Cache active.

I was able to reproduce this issue and made a change that should resolve the issue. When a user is logged in their cart/session ID is their user id and their cart is copied over, but the plugin had already cached the items with the original session id.

Can you test out the development version to see if it solved the issue for you before I push out a new release?

Will test today

Confirmed working now. Thank you!

Note: I didnt see the “Settings” link in the plugins page on this one.
