hmm,

http://order.dingo.net/ => Bad Request (Invalid Hostname)

sorry, you cannot do that

you can of course set preselected ingredients to be 0 , so if one removes it , the price will not change

or only allow one ingredient to be removed,

or even play with negative prices for a “no onion” ingredient for example.

none of this will give you exactly what you would want though

if you do you could alter the table like so

ALTER TABLE 'wp_wppizza_orders' ADD COLUMN 'user_data' TEXT NULL AFTER 'notes';

where wp_wppizza_orders should of course be the table name for your install
(i would make a backup first though)

this will not of course add multibyte support (actually even WP itself uses utf8mb4 now as of April 2015), but it should at least allow you to add to that table again (i.e save orders)

assuming that the mysql version is the issue and you have updated it , the table/column does not magically create itself.

to do that, do either of the following:
if there is a newer version of wppiza avilable, just update and it should create that column

if there is no newer wppizza version yet, do the following (for the purpose of this example i assume your current wppizza version is 2.15.0.10):

– de-activate wppizza
– open wppizza/wppizza.php
– on approx line 8 you will find Version: 2.15.0.10 change this to Version: 2.15.0.10.1
– on approx line 39 you will find define('WPPIZZA_VERSION', '2.15.0.10'); change this to define('WPPIZZA_VERSION', '2.15.0.10.1');
– save the file
– go to your plugins page and reactivate the plugin. as the version number is now higher than what there was, it will check the table structure again and update what needs updating

that should be it (i assume here that you know how to safely edit php files)

actually , forget previous.
just a quick look tells me your db table is missing a column

link to site please.
the errors you are posting above have nothing at all to do with what you are writing about and i suspect there are a LOT more entries in your debug.log

(though you might want to fix your server setup which is clearly messed up with missing or outdated extensions)

of course you can add multiple unless you restrict this
i don’t know what you tested / looked at.

have a look at the
https://support.wp-pizza.com/twentytwelve/ -> make your own pizza.

the first few groups have restrictions (as labelled) the “ingredients for £ 0.50” for example don’t and you can add the same thing as often as you like

@kaybee
for some reason i only just got (another) notice of your private post .
just ignore the test order i just placed (tried to check things that dont need checking anymore i believe)

>….in general settings i can set:“Deliver even…..
>..You can not add the option for this extension?…

you do not need to, it’s a global setting that applies

>In the current situation must look for something in store for 2 to have the opportunity to order.
because you set minimum order to 80….
