>Is WP-PIZZA plugins and extensions are Multisite compatible

sure.

as i already said you will need 2 sites (using a multisite setup perhaps ?)
https://codex.wordpress.org/Create_A_Network

if you have 80000 different users per day , then this would be normal i guess
if not, you should speak to your host as either your sessions aren’t working / setup correctly or you are under attack of some sort .

>or how can I share it with you?
just give me access to the plugin (packages) with my login and i’ll download it myself

First of all, thanks for the feedback.
Secondly – in no particular order – allow me to respond to a few things regarding your post

>> when i start typing an address down the street from the pizzeria the autofill box appears with completed addresses and once selected the appropriate one it will then fill in an address with a different street number a couple of numbers off

there isn’t anything i can do. addresses are chosen by google depending on where you or your customers are (one of the reasons why it is – and probably will always be – marked as experimental)

>>The google maps feature would keep the order page from loading at all without a Google Maps API key.

yes, I know.
until about a couple of months ago or so, an API key was not strictly required by google. this is not the case anymore and you will always need (and enter) one – i guess i should somewhat update the explanatory text in the plugin which I believe does not spell this out at the moment

>>add forced modifiers…
without at least seeing your site i cannot recommend/say anything.

all i can say is this:
there isn’t really a wrong or a right way of doing things. whatever works for you is what counts really.
however, i have also seen many installations/settings where the way ingredients/options were added could have been made *a lot* more efficient/simpler (mostly unnecessary duplication of things)

But, with forever more and more options added to the AI plugin comes also the possibility to overcomplicate things even if that would not be needed in many scenarios.

Unfortunately , there’s not much I can do there as I will certainly not take away existing options

In summary, the options are there, it’s for you to set/use them in the way it suits you. There are often different ways to do the same thing – all depends on your needs

>> it would be nice for them to have the ability to register an account…etc

this is already the case (and has been for months, if not years), but you must enable “anyone can register” (there are already many topics here on this forum regarding this) and enable/set the form fields you want to register (wppizza->order form)
that said, the users purchase history does not allow for re-ordering of previous orders as it is at the moment. this is one of the (many) added things that will be available in 3.x when it is released

I think that’s it for the moment from me.
In any event, thanks for taking the time to post your thoughts/experiences etc

>The problem is that is doesn’t show right on the order page.

for starters, i would suggest you switch to a default theme (like 2016 ) and check if you still have the same issue

> to replace the numbers of the additives with just an image
as you already seem to be doing this I don’t understand the purpose of the question to be honest

>Why did WPPizza take over my nav menu?

i can assure you it does not do that.

however, it might be your theme / a plugin / your menu settings that automatically add pages to a menu

you cannot make the first post of a topic private – reply to it (yourself) if you want to make some info private

there is no such thing as an “easy to built API” in whatever circumatsnces
