also, if that form is being used to sent spam, you should also get a lot of orders.
you were saying that the host had to contact you which sounds to me like you did not get any spam orders ……

PS: version 3 beta has been updated (although that has nothing to do with your issue, just mentioning it )
see blog.wp-pizza.com

try this line instead
curl_setopt($this->ch, CURLOPT_SSLVERSION, 6);
TLS lower than 1.2 is disabled on wp-pizza.com (for good reason)

forget that. this would affect the cloudprint itself, not the license screen. that’s something completely different. I misunderstood.

I’ll have to dig around a bit

which version of wppizza and cloudrpint plugin are you using ?

hmm, i know nothing about win servers really.
however – though that’s just a wild stab in the dark – you could try the following
(make a backup of the file you are editing – if it falls over revert to that backup)

in the plugin you find the following file

/inc/HttpRequest.Class.php

on approx line 49 you will find
curl_setopt( $this->ch, CURLOPT_HTTPAUTH,CURLAUTH_ANY);
right AFTER that ADD
curl_setopt($this->ch, CURLOPT_CAINFO, ''.ABSPATH . WPINC . '/certificates/ca-bundle.crt');

and save. let me know if that fixes it (or any other/different errors you might get)

please read the notes next to the “Printer ID” settings in WPPizza -> Cloudprint

try something like this in your functions.php

add_filter( 'wppizza_filter_orderhistory_order_info', 'my_orderinfo_add_total', 10, 4 );
function my_orderinfo_add_total($markup, $order_id, $customer_details, $order_details){
	
	/** add total after $markup['last_update'] **/
	$markup['last_update'] .='<div>'.__('Total').': '.wppizza_output_format_price($order_details['total']).'</div>';
	
	return $markup;
}

the cloudprint plugin does not set any margins (unless you specifically set them of course, but that’s not the default
if cloudprint itself does so , please refer to the documentation there

you must take out the

white-space:nowrap;
from
#header #blogname td

if you increase fontsizes globally without linebreaking things it will proportionally shrink to fit the page

the plugin was updated to that effect almost a year ago now. (June 2016 to be precise)

sorry, but i cannot help you
you are asking me to debug someone elses plugin

the datepicker shows up just fine if used normally on a wordpress website (yours too)

if it doesnt when used with your other plugin that makes your site into an app, you will have to ask them . i know nothing about how your other plugin does things
