I've installed the aweber plugin and am getting this on the "thank you" page after signing up. WARNING: constant() [function.constant]: Couldn't find constant _TPL_THX_AWEBER in line 117 of file common.inc.php Thank you for Signing up --------------------------------------- Then the aweber form: Email: rk@blah...com Name: Rashid But when I hit submit - Aweber throws a message telling me it doesn't recognise the customer: An Error Occurred Notice: Sorry, the account you tried to access was not found in our customer records. To notify the site owner of this message, push the back button on your web browser or check some of the selections below for more information. I've logged a support call, but as it's Good Friday here (and will be when Andrey gets this, maybe someone in the forum has an answer) ;-) Thanks, Rashid.
