Well I have solved this problem because I have found I have installed another SMTP plugin which ignores the values in the “use SMTP” “SMTP test” page of wppizza.

However I have purchased the bundle however there are two new problems.

1. If I as a customer use Paypal method, I can see the order success page and receive confirmation email. But if I choose Cash method, I cannot see the order success page, though there is confirmation email.

2. Now the tip box in this version is better than before (customer does not need to click OK button now). However, I hope it can take two values. One is any numerical number from 0 to any real positive number. Another is the word like “cash” , “CASH” or “Cash”. And you can make two click buttons “Cash”, “20%”. If Cash/20% is clicked, Cash and 20% of the total will be displayed on the Tip box. This is common setting for Eat24/Grubhub.

3. It looks like there is an error email with the following message even there is order success page, successful paypal payment and receiving, successful order emails in both buyer and seller.

======================================
BLOG ID: 1 – ORDER ID: 7459

Lastly, If you need the username and password to the website, please give me your email. Thank you. Xin

I used other browser without login and could see my private reply.

I did not see the Cash order problem after I upgraded the PHP to 5.6.

But I encounter a new error and I believe it should be already there, not related to version of PHP.

Below is a successful order paid by Paypal
Subtotal $ 5.00
Sales Tax $ 0.42
Tip $ 0.01
Total $ 5.43

Here is a HALF SUCCESFULL order by paypal

Description Unit price Qty Amount
Minute Maid Orange Juice $3.25 USD 5 $16.25 USD
Tip $0.05 USD 1 $0.05 USD
Discount – $5.00 USD
Subtotal $11.30 USD
Shipping and handling $3.00 USD
Tax $1.18 USD
Total $15.48 USD
Payment $15.48 USD

I as buyer have paid with paypal and received the notification emails from paypal in the seller email account.

But there is no order emails to buyer email or seller email.

Below is the ORDER confirmation (if successful) page on the website:
==================Start of page orders/?wpptx=……
Error

Apologies. There was an error receiving your order. Please try again.

Error Details
1001: amounts do not match: 15.48 != 15.49

==================End of page orders/?wpptx=……

So somehow the wppizza program examines the amount (I guess) returned from Paypal and found ONE CENT difference and caused the error.

In addition, “Shipping Tax @ 8.25% $ 0.25” is better NOT to show up in the final order confirmation. I think it is a convention.

http://www.eat24.com and http://www.grubhub.com are the two most popular websites for online food ordering in the united states.

By placing test orders without actually hitting the submission button at the last step, you will understand what I mean regarding the tip field and the tax on shipping field.

Here is an example which is forwarded to your dev wp-pizza email.
SUBTOTAL $20.45
DELIVERY FEE $1.00
TAX $1.77
TIP $4.64
TOTAL $27.86

The TIP is the default 20% and the customer wants to save time and does not bother to change it.
TAX=(20.45+1.00)*0.0825=$1.77
TIP=(20.45+1.00+1.77)*0.20=$4.64

It too complicated to show 3 lines for tax only.
