re empty categories:
if memory serves me right there was actually a/some reason why it shows “no results” in v3 instead of it being not shown at all.
that said, as i cannot really remember what the thinking was behind it, i will add an option in the layout settings that will be enabled by default, but can be disabled again if needs be, to the next update of the plugin which will not show empty categories (as that kind of makes sense to me too)

re placeholder image:
the classes are pretty much the same. but it’s not using an image but a font/content, so you’ll have to override the .wppizza-article-image-placeholder:before pseudo selector

date format : controlled by wordpress (wp-admin/options-general.php)

the rest , look again. i can assure you its there
wppizza->order form settings

>Just updated preorder plugin, and now it works like a charm.
good stuff

>Thanks and have a nice one.
no problem, you too

thanks.
one last question.
do you get this warning all the time or only on specific dates/times ?

reason i’m asking is this: eliminating that warning is easy, but am trying to find out why that array the warning refers to could ever be empty in the first place

(my guess would be: on mondays only, but confirmation of that would be helpful)

sorry, but i cannot see this happening anytime soon, as you’d/we’d be opening a big can of worms regarding sort order etc if one were to then allow saving of those searched for ingredients displayed with all the others omitted

that said, a simple CTRL+F should kind of work in many cases too and is all i can offer here at the moment

ok.
it’s just an – inconsequential – notice really, but i can easily eliminate this in the next update
thanks for flagging it

re 1) wppizza is simply a – so called – custom post type of wordpress and that’s how wordpress works (i.e editor, admins etc etc ) regarding giving access to certain things for certain roles

re 2) prices ARE rounded to the number of decimals your currency has/supports.
i.e
if your currency supports/has 2 decimals, fractions will be rounded to 2 decimals if needed
if your currency supports/has 3 decimals, fractions will be rounded to 3 decimals if needed
if your currency does not support decimals, fractions will be rounded full integers

This will not change.

The plugin has a filter hook included you could use to send to different printers.
please see here:

regrading a different template for each copy, that is currently not implemented I am afraid

generally it depends on the location of your store whether this would work.
that said, it really is mostly only an issue in places such as Kasachstan, Korea etc etc where google is not allowed to supply their services or streetmaps simply do not exist(yet)

generally, this should not be an issue in the US (and I know there are plenty of people that are using it there)

hope that helps
