Description: By clicking on 'Add' link in the 'Related issues' section on issue detail page nothing happened. No error in log was found. The link pointed to issue itself. For example 'https://[server]/issues/3035#' is the link which will called by clicking on 'Add'.
Note: I updated from 2.5.3 to 2.6.1 via svn switch prior this day. So maybe the defect is related to this update.
