Thank you, Robin, for finding a viable solution. I unchecked the blog option and it immediately worked as intended.
They only support pro versions and this site isn’t using pro. But I noted on their forums that they are having lots of problems with custom posts. I will monitor the wp support forum for their free version.
I reverted to the previous version of TEC and topics are now visible. I did have the most recent update. Thanks for the quick reply.
