Q1: The transaction states: “Wrong transaction” “Someone attempted a sale using a manipulated URL” under Logs.

I have successfully installed 1 product, with the button code on the form, which redirects to PayPal and allows me to complete payment. I set the product to be “Download link in Email”.

However, I never received an email, and under Logs, the transaction states: “Wrong transaction” “Someone attempted a sale using a manipulated URL”.

Answer: This problem is always caused by a mistake configuration in PayPal IPN options, from email section. Please check there is no space in the end of your email.


Q2: How can I change the default currency?

When adding products within the component, the price field has USD currency symbol beside this, without any options to change the currency.  I will be selling in EUR – how can I change the default currency?

  1. Go to your website host root folder, locate the file: /www/yourwebsite.com/plugins/content/pinpbutton/pinpbutton.php
  2. Edit the file and find the line: <input type=\"hidden\" name=\"currency_code\" value=\"USD\">
  3. Change USD to EUR
  4. Save the file

 Q3: How to upload file which is bigger than 20MB??

After uploading a zip-File we get the error message: "Error: Uploaded file size is bigger than 20M!" - is there a possibility to change the allowed upload size?

Answer: If you want to upload big files, we suggest you to upload them by ftp software, because it is unstable to upload very big file by HTTP upload. I am using "FileZilla" to upload big zip files to my server. You can follow these steps to do it:

  1. Creat a sample text file and rename it as same as the file you want to upload. For example, myvideo.zip
  2. Add your digital product with this fake product file
  3. Open your ftp software and find out your extension Joomla administrator folder, the folder location will be /www/yourJoomlaSite.com/administrator/components/com_pinp/pp_dg_upload/
  4. Upload and replace the face file with your real zip file

 Q5: How can I set tax information?

I already make the extension working properly. But where can I set tax information in the component? For example, in Singapore the price must include 7% tax.

Answer: The component doesn't provide a way to set the tax information for each product, but you can set tax information for all products globally. You can tax with following steps:

  1. Go to your website host root folder, locate the file: /www/yourwebsite.com/plugins/content/pinpbutton/pinpbutton.php
  2. Edit the file and find the line: $taxRate = 0;
  3. If you want to set tax as 7%, please change it as $taxRate = 0.07;
  4. Save the file

 Q6: Why do I get "Duplicate Transaction" error in log?

I connect my extension with PayPal sandbox account for testing. But for testing, I get lots of "Duplicate Transaction" in my log page.

Answer: The extension is working with PayPal IPN. For each PayPal transaction, PayPal will send an IPN notification to the IPN URL, which you have set in your PayPal account. With this notification, the extension will be triggered to send email with digital product to your customer's email. In production way, PayPal will send the notification and the extension will save this notification in the database. To make it safe, if the extension gets the same notification, it will not send email and product, but record a "Duplicate Transaction" in log page.

In the PayPal sandbox environment, it allows to send the same notification for testing. In this case, the extension will record "Duplicate Transaction" error message.
