sorry, but i do not understand what you mean by “compiled automatically” or what it is you are expecting when and where

until wppizza v3.x, no additional gateways – other than the ones already available (https://support.wp-pizza.com/gateways/) – will be added I am afraid.
Once wppizza v3.x is released, there is definitely a plan to add more gateways in due course. However, which one will be available when I cannot tell you.
In the meantime, there is a skeleton gateway in the plugins add-on directory you could use to develop your own if you wish (wppizza v2.x)

sorry, but that’s not likely to happen anytime soon (if ever)

not only are there so many possibilities and permutations that it will most likely confuse those non-technical users in the first place, but the layouts available will probably also need some tweaking (using css for example) to make them work with the theme used when setting things up
(that’s just off the top of my head, I am sure there would be other things that neede to be considered )

furthermore, there is always a possibility that shortcodes change or – more likely – are added at some point
for instance from version 3.x onwards – when that is released in the not too distant future – you will be able to mix and match layouts for different pages (plus a bunch of other things)
trying to maintain yet another option with the inevitable request for more granularity will take way too much time away from adding other – and in my opinion more useful – additions

lastly, understanding shortcodes is somewhat essential if you want to set up any kind of wordpress site (barring the most basic ones)

that’s not to say I will never look into it, but I just cannot see this happen in the near future

if you are referring to this
>https://support.wp-pizza.com/topic/post-code-validation/
then no, there has not been any development afaik (i.e stripe still do not allow for this sort of thing in the popup ….. unless someone tells me otherwise)

check what the your script actually outputs ( file paths etc )
moreover, this will only work on the orderhistory page as it’s coded btw (but you could adjust that )

i know this works on many installations

PS: Just a heads-up. this will be actually a clickable option in wppizza v3.x (not much longer until a beta will be made available – just doing some tidy up, testing as much as i can and updating the various extension to work with it)

>I can’t replicate the error 500.
it’s on ALL of your pages . look at the console (in Chrome ctrl+shift+i or F12)

what you have to sort out before anything else

on https://rural-lunch.co.uk/orders/
(in console)
https://rural-lunch.co.uk/wp/wp-admin/admin-ajax.php 500 (Internal Server Error)

500 error could be anything – but it’s never good – so you will have to check your debug logs

>The plugin has worked fine up until last night…
in which case clearly something else is at fault here as *i* certainly did not change anything.
my first guess would be a server/software/firewall update perhaps or some such thing.
goes without saying that the plugin needs to be able to access google’s servers
this is a hosting/server/connection issue , not a plugin issue

>re: debug logs
mostly of course not from wppizza plugins. in any event these are just notices and inconsequential
