I have already reinstalled the workflow server, but it did not work. What can I review?

Re-installing Workflow server will not help. There is an Autoindex configuration in the system causing problems, or the list of Tasks has an invalid entry. I suggest that you enter a Support Request so that support can look in to the problem for you.
