Ajax functionality stopped working after updating to version 8.1.5

[elsassupport]

Hi,

I recently updated the WP Estore plugin to version 8.1.5. But after updating, the Ajax functionality to add or remove items from my cart has stopped working. If I turn off the setting “Enable Ajax on Add to Cart Buttons” adding and removing items works fine.

Things I checked/did to try to fix:

– I checked the console in chrome and the Ajax request does not give any errors when adding an item to the cart, I receive a 200 status code from the request and the data response seems normal. But when I go to the cart it is empty.

– I deactivated all plugins and switched to a different theme, this didn’t seem to fix the issue.

– Don’t see any major errors in the debug log except:

[28-Mar-2020 13:24:46 UTC] PHP Notice: Undefined index: variation1 in …/wp-content/plugins/wp-cart-for-digital-products/eStore_ajax.php on line 94

Since all of the listed errors are contained in 1 particular file; perhaps the download was corrupted. Please try re-downloading another copy of the plugin.

It is likely something with the variation configuration is going wrong here. I will take a look at your site to see your setup which allow me to understand the issue. I have sent you an email for it.

Hi,

I looked at all the caching and made sure nothing was being cached. However this did not fix the issue.

I did some more research and found that in your code of the plugin you are not calling session_start(); when adding or removing an item from the cart. If added the function on line 74 and 162 in eStore_ajax.php.

Now the cart seems to work just fine.

Thank you. I have made some improvements for this after your feedback. That should resolve this.
