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)

v2.1 of the timed menu should now read the translations (again).

Note: the textdomain/pot/po/mo files have been shortened to wppizza-timed-menu.[po|pot|mo] as there is really no need for it to have an unnecessarily long filename / string there
so no more “wppizza-timed-menu-locale” just “wppizza-timed-menu”

actually in the timed menu plugin , there is an error on that front from an earlier version – i’ll correct that during the course of today
The postcode one however is just fine here

where can i see this please ?
works fine here

re 1+2:
you are ignoring the fact that opening times can cross midnight. So, no, on both counts

re 3:
The holidays option in the main plugin was added relatively recently and the current version of the preorder plugin does not account for that. I completely agree that I need to account for the holidays settings there too.
Thanks for pointing that out (Cannot give you a distinct ETA yet as to when this will be done, but hopefully not before too long)

>….I can post this on the extension forum if necessary…
No need, but thank you for the consideration

you are looking at the wrong plugin
i am talking about
https://www.wp-pizza.com/downloads/wppizza-delivery-by-postcode/
(just happens to have the same verion number now as the ingredients plugin)

yup yup, understood.
should be relatively easy to fix (though was all a bit obscured as the ingredienst plugin – using the same popup script library – was masking things somewhat )

quick update:
I can reproduce this here too with a clone of your site (that’s a good thing) Just need to find out where the issue is – but that will have to wait ’til tomorrow as it’s kind of late
