PHP 8.0 errors with Mini-Cart and Cart powered by BC4WP

[ll-r-magner]

Expected behavior

Updating wordpress to PHP 8.0, expected nothing to break outside of my custom code.

Actual behavior

Updated to PHP 8.0 and fixed all errors and warnings inside custom code. Bigcommerce Mini Cart and Cart Page are not functioning.

• Mini cart always showing as empty.
• Cart "remove" button not functioning
• Once cart refreshes after "remove" button was pressed it shows empty cart even though there are more products in cart left.

Steps to reproduce behavior

1. Updated wordpress php to version 8.0 from 7.4.
2. Astra parent theme
3. Using BC4WP plugin to run our mini-cart and cart

Workaround or possible solution

We can maintain the site on PHP 7.4 until January 24th 2023. Then we will have no choice but to upgrade to 8.0.

Disregard, im sorry for assuming it was the plugin. I was using Kinsta wordpress debugger mode and it was causing conflicts with cart functionality. All is well. Cheers.
