When I post an offer to buy, and someone accepts, I get a Java exception null pointer and the log file shows “SignaturePubKey in message does not match the SignaturePubKey we have set for our trading peer”. What does this mean? How do I fix it?

Did you have any bugs or did anything non-standard? This log means that the data are not as expected which seems that somthing is wrong (e.g. if you have deleted your signature keys but kept your offers).

My email address was incorrect in my currency account. So I deleted that and recreated while putting the offer together. That probably caused the issue.
