2checkout callback not workign

[chewy]

am i doing something wrong? When i complete an order in 2checkout, I have the approved URL set to my callback url but the page is blank when the order is completed. I have demo mode turned OFF in whmcs but demo mode turned ON in 2co.

The invoices aren't getting marked as paid. Not sure what's going on here.

I had to remove the secret word entry from within WHMCS, and then everything worked for me. Hope this helps.

Wonderful, you've saved me hours, after removing the secret word, redirected as needed.
Thanks much!
