Please note: Two developers have already failed at identify my issue. Good Woocommerce / Wordpress knowledge is required. Don't waste your and my time.
I updated my Woocommerce shop, among updates was plugin: "Product Bundles". This plugin had to update database and in this process, my custom developed plugin "eurocoder-woo-bundle-shortcode" broke. I need it to be compatible with Product Bundles again.
You will need to identify what Product Bundles changed and change code of my custom plugin to make it work again. Cheers
