Thanks
I had set permissions based on the UBB.threads Install Guide but it did not cover entries displayed on the permission check page in Control Panel. For example templates/ directory was set to 0777 but templates/default was still 755 and the files within default/ were 0644. I went through and set the permissions for the subdirectories and file contents and then permission check reported OK but it does not help with the submit button error.
There is one file test.php in the Includes directory that will not allow a permission change from 0644 to 0666. I can edit and rename the file. The other include files are fine.
