Errors when clicking on Paypal IPN | Transactions

We changed our site to use SSL yesterday so we now have a new IP address. Everything was working before, but now when I click on Paypal IPN | Transactions I get the following errors:

*******************

I changed SSL back to false in the configure files and double-checked for blank lines at the end of the files and still get the same errors. I saw a post in a newsgroup that makes me wonder if the IP address change has anything to do with it, but I don't understand cookies well enough to know.

Any help greatly appreciated! Thanks!

Looks like I didn't have all the SSL info set up properly. I made sure everything that looked like it needed a value in the configuration.php files had one and now it works. Great piece of software. Every problem I've had so far with one small exception is due to my oversight or lack of knowledge. Most I have solved by reading the forums.
