I noticed that all of the files in cache (other than index) were dated the day I did the upgrade. I deleted them. I noticed that the index file permission was 644. I changed it to 666. That file was not listed as one to check in the install guide.
The new post/topic areas are now correct.
I have to get some other work done and get to a meeting. But I will go through and do the other files to 666 and directories to 777 later.
Thank you all for the help.
