Thank you for your response!
I agree that it would be nice if clients did not use nicknames when signing up but I can think of no good way to stop that.
For example people named Wiliam frequently go by Bill and that's how they signup, not thinking future payments would require a credit card with William on it. At least when it comes time to fill out the checkout fields they know to make it match what's on their card - but it isn't obvious they need to make that 'invoicing address' section match too. After I turned it on yesterday, a client signed up and didn't know to modify the details of that window too and the payment was rejected. I have high hopes that once you add the address fields capability to Paypal Pro, and the invoice address can be turned back off, that having the checkout details all being filled out in one area will resolve the issues. Thank you!

Thank you for the fast update!
We also maintain an older site on joomla 2.5.28 with a lot of custom code preventing is from doing a simple joomla update to 3.x.
Is it ok to run the most recent builds of CB and CBSubs on 2.5.x?

Our main site (joomla 3) has the most recent builds of everything, just curious if the newest CB and CBSubs will work ok on an older joomla site.

Still having a problem with Paypal Pro on our site that's running the most current versions of joomla and CBsubs. We get the same IPN error when the recurring charge is processed. It fails to report the charge back to CBSubs. The error is: paypalpro Paypal IPN fraud attempt. ERROR: paypal subscription IPN type subscr_cancel for a basket without auto-recurring items: Invalid transaction. Please contact site administrator to check error log.

The error makes no sense since it does have a basket with an auto-recurring item.
Paypal team has looked into it and said: 'According to our logs, all the IPNs are getting delivered to your IPN url which are generally of the following forms:

advisors4advisors.com/index.php?option=com_comprofiler&view=pluginclass&plugin=cbpaidsubscriptions&cbpgacctno=5&do=gw&result=notify&format=raw

We are not seeing any IPN which have been failed from our end. '

Oddly, the outdated version of CBSubs running on our outdated joomla receives the IPN report back correctly! I have triple checked that the url assigned by cbsubs is configured correctly in Paypal and it is. Any ideas are appreciated.
