Yeah ok. Nice rubberduck session.

I answered my question in my own question:
> the nonce is regenerated by check_ajax_referer() with the same UID, time and action – it is not retrieved from some session storage. Thus, it tries to validate a nonce that is generated with a new random or time value… and therefore fails.

Closing as I completely missed the point 😛

I have had replaced the plugin manually actually to the latest (your) version right after the auto-update but, please check again that this is really not your version.

It came from the wp org. Our server admin confirmed this. So if the version doesn’t exist…. The problem is not on our server.

Hi, thanks for the answer.

No, not really – I just would like the default email that WooCommerce has for when an order is complete, to work. Actually, I have this exact issue here (as many other users seem to have):
https://wordpress.org/support/topic/order-complete-email-not-sending/

However, in our case, it does not work even without any other plugins nr with StoreFront Theme

I managed meanwhile to force-send an email using wp_mail() on the woocommerce_order_status_changed hook, so that part is resolved, yet, the default WooCommerce “Order Complete” Email, still does not send.

This is true even if only WooCommerce, Veeqo Integration Plugin, and Storefront Theme are active.
All other emails, work just fine.

Ok so this was as expected on me

The IN rule does indeed search in an “OR” fashion inside the single taxonomy.
And the outer AND does indeed connect the taxonomies themselves properly.

My mistake was, I had some mess in my code that pushed an empty array with an empty key to the query when any of the taxonomies had nothing selected (since the Query Param itself is there nonetheless, I had to put in a check to NOT push an empty array with an empty key in those cases, but indeed nothing instead)

To illustrate that, what I produced was:

[tax_query] => Array
                (
                    [0] => Array
                        (
                            [taxonomy] => geography
                            [field] => slug
                            [terms] => Array
                                (
                                    [0] => afghanistan
                                )

                            [operator] => IN
                        )

                    [1] => Array
                        (
                            [taxonomy] => access-control
                            [field] => slug
                            [terms] => Array
                                (
                                    [0] => 
                                )

                            [operator] => IN
                        )

                    [relation] => AND
                )

Instead of this:

[tax_query] => Array
                (
                    [0] => Array
                        (
                            [taxonomy] => geography
                            [field] => slug
                            [terms] => Array
                                (
                                    [0] => afghanistan
                                )

                            [operator] => IN
                        )

                    [relation] => AND
                )

(for when one of the inputs had no selection (as you can see one of the arrays presented an empty terms array key)

I still have 2 problems thou

1. In the query, when I dump it, I can see the query_vars key tax_query is properly populated with any selection I make
2. But in the query’s tax_query key, any terms I pass with a multiple checkboxes selection are again left empty:

[queries] => Array
                (
                    [0] => Array
                        (
                            [taxonomy] => access-control
                            [terms] => Array
                                (
                                    [0] => 
                                )

                            [field] => slug
                            [operator] => IN
                            [include_children] => 1
                        )

                    [1] => Array
                        (
                            [taxonomy] => geography
                            [terms] => Array
                                (
                                    [0] => afghanistan
                                )

                            [field] => slug
                            [operator] => IN
                            [include_children] => 1
                        )

                )

            [relation] => AND

_even if I have the proper selection in the query_vars key tax_query!_

And yet it produces the right results. Now that puzzles… but I believe it is connected to an error I see in the logs related to PHP Warning: urlencode() expects parameter 1 to be string, array given in /public/wp-includes/formatting.php on line 5525

I am doing something wrong with the multiple checkboxes I fear. I guess from here I can debug it 😀

Thanks for the handholding and listening.
