 * Hi, I have an Approved to Sell account with 2checkout. I followed the integration
   instructions on their site. Inserted all the user ID, secret word, Approved URL/
   INS URL info, etc. etc. And I still get the error:
 * ERROR CODE:PE101
 * Any idea what might be happening here?
 * Thanks.

 * hey,
 * please double check Mode option. You seems using Demo SID on live or Live SID
   on Demo.
 * Thanks.

 * I have Demo on both 2checkout and the plugin. I opened a support ticket with 
   2checkout and they said:
 * “The PE101 error is caused by an incorrect or null value passed for the “sid”
   parameter – please review your cart’s settings or site’s HTML forms to ensure
   that you have correctly entered your 2CO account number as the “sid” parameter.”
 * I am using the correct ID and Secret Word… I have no idea what can be going wrong
   here.

 * Are you aware of invoice specific payment settings? They may appear different
   from general on settings page. On edit invoice page go to the bottom of the page
   and find there payment settings and check if they are correct.
 * Thanks.

 * The settings on the bottom of the invoice are both set to:
    Default Payment Option:
   2checkout Accept Payments: 2checkout
 * Is there a way to “hardcode” my merchant number into a php file?

 * No, hardcoding is not a solution.
 * Let me know what you have in here [http://screencast.com/t/79YmtFL7SQv](http://screencast.com/t/79YmtFL7SQv)

 * I blurred out the actual client number and secret word, but I have triple checked
   them and they are correct.

 * Are you trying to test? I see you use Demo mode. In that case you need to set
   test account details but not client actual.
 * If you don’t need to test then set Demo mode to NO.
 * Thanks.

 * Yes, I need to test.
    what are test account details?

 * You need to sign up here [https://sandbox.2checkout.com/sandbox](https://sandbox.2checkout.com/sandbox)
   to get test environment and payment details. That’s not connected to the plugin.
