Delivery type (WPPizza -> order settings) must NOT be “No delivery offered / pickup only”

Ok then.
To do what you were asking you need to do 2 things (will require wppizza 3.18.10+).

a) use the shortcode to display the pickup/delivery toggle wherever you want to display it
see : https://docs.wp-pizza.com/shortcodes/?section=pickup-choices

b) you must also add the ‘wppizza_filter_force_pickup_toggle_display’ filter ( as outlined here https://docs.wp-pizza.com/developers/?section=pickup-opening-times under B) ) – it will not work without it if you are not displaying the cart anywhere

c) Naturally, you will also need the pickup prices plugin to display the prices as appropriate depending on pickup/delivery selected

Re Styling: Just use css

Hope that helps

Firts of all, it really kind of depends on what (wppizza) version you were updating *from*.
That said, I cannot see the versions of the other plugins you are using causing too much of an issue, but you should enable debug and find out what your issues are.

https://docs.wp-pizza.com/troubleshooting

Furthermore, when you are saying ” getting version 3.8.2″ , I do not know what plugin you are actually referring to. If it’s the main wppizza plugin, send me an email to dev [at] wp-pizza.com and i can send it to you (but as mentioned, I do not actualy think that would solve any issue you are having )

turns out the issue was (seemingly) neither in the gateway, nor in the stockmanagement but in the main wppizza plugin.
I believe wppizza 3.18.9 should fix this (but let me know of course if you still have issues please, thanks)

ok, no problem.
can you quickly check the following on your main site.
can you disable the wppizza stockmanagement plugin and do a quick test (test or live ) and let me know if it works then

some info regarding version numbers as alluded to above:
https://docs.wp-pizza.com/faqs/?section=removing-version-numbers

thing is , it works all fine here with or without tips.
You have however removed all version numbers . although personally i think this is a bad idea in any event, have you made sure you cleared your cache before re-testing ?

a few things:
to start off with, i would suggest you update your plugins to the latest versions
secondly, when i use a bogus card on your site , i get all the right errors in the console (though i somewhat think they should actually be displayed somewhat too – I’ll look at that )
things like
field: ‘cardNumber’, message: ‘Credit card number is not valid’, type: ‘VALIDATION_ERROR’}
are coming directly from square not from myself/wppizza so this leads me to believe something does not get passed on (as the credit card form is also generated by square, I do not think I can do anything about that in any event)

that out of the way, once you have updated your plugins, have you tried using test credentials , put the payment in test mode and used a test card ? (i.e 4111 1111 1111 1111) .
Whats the result ?
Have you disabled all other plugins / used a default theme ?
(As mentioned this works all fine here and as intended, so there;s something in your particular setup)
