>I honestly don’t know what else I can do. Caching plugins were already disabled
maybe you were logged in (as admin) so you never saw the cached version. in any event – at least on your staging site – i am also now getting uncached and unminified content.
(might have been caused by some cache refresh time settings or something . who knows.)

However, doing exactly what you I understand you had problmes with , it works there just fine now from what i can see.
I.e I type in “122 marin pl” , hit enter and it sets the address to be “122 Marin Place, Woodland, CA, USA” – i.e the first item of the dropdown available – as well as setting the delivery charges accordingly….

the first thing you need to do is turn off all your caching, minimization etc plugins or we have no idea what we are looking at

>I use Version 5.0.17.
ok, good

>On this screenshot, should I see the options for the ingredients?
no. you should see a separate “Ingredients” link on the left under the “Tools” link
as in this screenshot

i cannot see in your screenshot if it’s there as you cropped it above where it would/should be

(PS: I agree , the description on the screen you are seeing that says – “please go to wppizza->settings->ingredients …. etc” needs to be updated somewhat in the not too distant future, but that does not affect the functionality of it of course)

the issue i’ve been talking about HAS something to do somewhat with using arrow keys / enter keys / tab keys etc
whether or not this will be exactly your issue i cannot tell you right now.
i’d suggest updating to the latest update when it’s available and check it then (and – in fact – let me know either way afterwards )it’s a bit of a trying to narrow things down somewhat (there are almost countless ways to interact with this thing with the setting of various options)

>Please watch my uploaded video and test again. I tested it on multiple desktop browsers (Chrome, firefox, safari) on both Mac and PC, the problem still exist.

did exactly that on your staging site
i.e typed in “122 marin pl” then simply used the mouse to select the address from the dropdown available there . again , this worked just fine so cannot reproduce that particular issue (then again , in your video i cannot see any selection by the mouse on the dropdown , though that might be because of the way the video capture worked)

However, when messing around with things i did find something that *might* explain what you are seeing in your setup/scenario – even though I cannot reproduce this from here

give me until later today or tomorrow to make an update of the postcode plugin available and test things with that update. *perhaps* this will sort out your issue (and if it does not , at least I am certain it will fix some issues that might occur for others now or in the future)

a) post_theme_setup is not hooked into / called by *ANY* wppizza plugin
b) you are using wppizza_on_order_execute v2 coding with v3 of wppizza

https://docs.wp-pizza.com/developers/?section=action-wppizza_on_order_execute

in fact i am even surprised that your coding works at all – i would suggest – for starters you get rid of

$order = new WPPIZZA_ORDER();
$order = $order->session_formatted();

as you are overwriting the whole purpose of having this as parameter in the hook in the first place

furthermore
add_action( ‘wppizza_on_order_execute’, ‘print_order’, 1);
should be
add_action( ‘wppizza_on_order_execute’, ‘print_order’, 1, 3);

if you want to access all 3 parameters

please refer to the wordpress codex regarding priorities and (number of) parameters of filters/action hooks

ok

there isn’t really any provision for that in the plugin at the moment (other than skipping the installation of default items and categories entirely – see install constants here : https://docs.wp-pizza.com/developers/?section=wppizza_install_constants)

but i’ll make a note of that idea and perhaps add a couple of filters in the next update that would allow you to overwrite the default items/categories etc)
