I have the WorldPay module running on a live site, in live mode (testMode set to '0' in admin) with the WP account in live mode.

For some reason the call back script is returning the string "This is a TEST TRANSACTION. No money has changed hands" even though 'testMode=0' is being sent to the it by WorldPay for each transaction.

Has anyone else experienced this?

TIA
