Symptoms

The Create button is missing from the "Create Issue" screen. Thus, users can't create issues from the UI.

Cause

There is an invalid action ID in your workflow definition. The create (or first) action in the workflow is expected to have an id of "1".

Resolution

1. Download the workflow XML.

2. Look for XML like the following:

   <action id="1010" name="Create Issue">
   

3. Replace all instances of the bogus action ID with "1".
4. Import the XML as a new workflow.
5. Migrate projects to the new workflow.
