FAQ and Troubleshooting

I've enabled the demo mode in 2Checkout account settings, but it doesn't work.

Make sure that the Account Demo Settings located in the 2Checkout backend → Site Management page is set to "Parameter".

Possible values of this option are:

  • On: Using this setting all sales will be treated as demo, regardless of any parameter value.
  • Off: Using this setting all sales will be treated as live, regardless of any parameter value.
  • Parameter: Using this setting a demo parameter sent to the purchase routine will control the demo setting.

Please use the "Parameter" value.

How to find this option: after you have logged in to your 2CO account you will first need to click the Account tab, and then click the Site Management sub tab on the Account page.

I get the "Order # has failed: MD5 signature does not match" error

The MD5 error means that the Secret Word you specified in the Control Panel (Settings → Payment → Payment Methods→ Account details for 2Checkout payment method ) does not match the Secret Word set on Account → Site Management in 2Checkout backend. Check what Secret Word you have in 2CheckOut and copy it into the settings for the 2CheckOut.com payment method.

I get the "PE101" error

This is a very common error, but it is extremely easy to fix.

During step four of the setup process, you're prompted for a SID, also known as your 2Checkout account number. This is numerical value, nine digits long.

Error PE101 is triggered when the user enters something other than a numerical value, or they enter the wrong numerical value.

To resolve:

  • Open your Control Panel
  • Click Settings → Payment
  • Find the Credit Card: 2Checkout listing under the Payment Processor column, click Enable and then click Account details
  • Enter your SID (2Checkout Account Number)
  • Enter your Secret Word (Must be the same value entered on your 2Checkout Site Management page)
  • Enter your Supplier Display Name (Company or Store Name)

Once saved, you should not see this error.
