Error Log

Thanks for sharing this. I definitely want to minimize warnings like this and it’s an easy fix, but I’m curious how that case is ending up. At least in the WooCommerce core there is no instance that filter will ever be called without passing in a $product_id

Do you have any other WooCommerce plugins installed and what versions of WooCommerce are you using?

I have a bunch of plugins for my client. It’s not my first choice but we are trying to get their site perfect. Your plugin probably saved the most headaches!

Wow, that is a lot of plugins. Presumably one of them is catching that same filter and not handling it properly, but I’ll fix it so the warning isn’t printed anymore for the next release.

Yeah I know it’s against my will to use so many, but it is a complex site. Any help is appreciated to see if there are any conflicts.

Aside from the warnings are there any other issues? I don’t have a lot of those plugins so I would have no way of testing.

The warning is safe to ignore, my function is expecting a parameter to be passed (even though it isn’t used in the function). So without it there it doesn’t affect anything other than throwing the warning.
