then it should not output anything anywhere unless it gets overwritten elsewhere

in any event, you can add the following (which will be default in th enext update anyway, so feel free to edit the core file)

in wppizza-delivery-by-postcode.php approx line 485 you will find the following

function wppizza_dbp_user_register_saveupdate_meta($ff){

right after that , add

if(!is_array($ff)){return $ff;}

so the whole function reads

	function  wppizza_dbp_user_register_saveupdate_meta($ff){
		if(!is_array($ff)){return $ff;}
		$ff[]=$this->wppizza_dbp_output_array();
		return $ff;
	}

which should get rid of that warning

you should never output error/warnings/notices but log them instead. (as outputting them will stop sessions from working amongst other things)

that said, i will fix this warning in the next update of course. for the time being though change

define('WP_DEBUG_DISPLAY', true);

to

define('WP_DEBUG_DISPLAY', false); in your wp-config.php

my guess is that your tag cloud does not look at and/or search in custom post types (in this case the CPT being wppizza)

you can also try:
wppizza->tools->repair categories (read the text next to that option , i suspect you are a victim of that issue)

and here
https://support.wp-pizza.com/topic/one-of-the-stranges-bug-i-ever-see/#post-9975

if the above is the case and you can shed light on that somehow (i .e what did you do before this occurred, any plugins running that – when disabled – makes the cats show up again etc etc , i would be very interested to hear it)

then all those 5 are doing it wrong.
try this one

https://wordpress.org/plugins/theme-my-login/

for the time being:

wppizza-gateway-mygateway.zip

basic skeleton gateway to implement your own gateway credit card implementation according to your gateway API

unzip and replace filenames and instances of “mygateway” as required and place into your plugins directory

read the comments in the files, update/edit/changes as necessary

currently only documented for hosted payment pages (i.e redirection to gateway for payment) – ajax overlay docs will follow in due course

although gateway implementation may change in the future , i will still cater for this way of implementaion if at all possible

thanks for posting.
happy to hear this can also be made to work with these kind of printers

that’s what this one does

licence looks all fine here,

>We have the “WPPizza – Add Ingredients Extension – up to 5 Sites License”
but from what i can see, this is a single site licence…
my guess is, you still have it registered elsewhere perhaps (whence the in-active) ?

if you want to add 3.00 to every item on delivery, set delivery costs per item to be 3.00 in wppizza->order settings->Delivery Charges per item:

and then use the filter above to count the items for which you do not want to add those 3.00 and substract them again
