Donation as custom field not added in cart

-- HikaShop version -- : 3.1.1
-- Joomla version -- : 3.7.2
-- PHP version -- : 7.1.6
-- Browser(s) name and version -- : chrome, firefox

Hello,
I've created a custom field for donation (see screenshot parameters at http://prntscr.com/fjb7v6 )
the frontend page for donation is correctely displayed (see pic screenshot at http://prntscr.com/fjb93p )
But impossible to add the product "donation" and the amount amount in cart (it ok for others normal products)
The parameters of the product seem correct (screenshot at http://prntscr.com/fjbao7 )
Can you tel me where is the matter
Best regards
Alain

Hi,
I'm sorry, but i didnt find where is "WAF" configuration (nothing like that in Joomla! 3.5 admin and in hikasop 3.1.1 configuration)
Can you tell me more about it ?
Thanks
Alain

Hi,
Admin tools was not installed. i did it but nothing about ajax.
The hostin company just tell me there is no error in PHP status on the server.
I add, i use hikashop v 2.3.2 for my online site (that i want to replace) for 5 years now, with the same products and same donation custom field which works perfectly on the same dedicated server !
My question is : Is there a particular setting to make (ajax, ...) for the domain environment (I use plesk)
If no, any other idea ?
thanks
Alain

Hi,
Im sorry, i use Hikashop business 3.1.1 (see at prntscr.com/fn6ago ) !!!
I ave 2 sites : the old one with the 2.3.2 (joomla! 2.5) and this one under construction with 3.1.1
So the screeshot come from this one and from anywhere else (I can create privately access to the administration so that you can see it) New screeshot at prntscr.com/fn6e60
For your last point, i see nothing about cart unerd advanced tab (see at prntscr.com/fn6fey )

Ok, i put it on.
That's a little better but when add donation in cart i get the following error message "Unknown column 'amount' in 'field list'"
Parameters of custom field seem correct :
detail amount : prntscr.com/fo88le
detail product prntscr.com/fo89al
Any idea ?
Thanks

Bonjour,
Merci, ça marche parfaitement !

Question esthétique : le formulaire d'enregistrement étant assez basique, existe-t'il à cotre connaissance des extensions gratuites ou payantes de formulaires d'adresse plus élaborées et compatibles hikashop ?
Sinon, où paramétrer les éléments suivants ? (voir capture écran : prntscr.com/fongmq ):
- réduire l'écart (trop important) entre le label et le champ
- augmenter l'espace entre 2 lignes du formulaire (champs collés les un sur les autres)
- remplacement du texte de validation du formulaire "suivant" par un "bouton" plus visible (cadre, couleur, gras...)
- la possibilité de mettre certains textes de label en couleur, gras,italique,... (comme pour l'option encadrée qui dont être impérativement cochée)
Cordialement

Désolé, j'y ai pensé ... après l'envoi !
J'ai tous les éléments pour modifier le formulaire.
Toutefois, je regrette que la version business ne propose par défaut ou en option un template de formulaire un peu plus esthétique, voire paramétrable ; l'enregistrement du client étant une phase importante dans le processus de paiement.
Merci pour votre réactivité.
Cordialement
Alain
