      When on the /configure page when trying to upload a new image to /userContent using the sidebar-link plugin the following error is generated.

      HTTP ERROR 403
      Problem accessing /plugin/sidebar-link/upload. Reason:
      No valid crumb was included in the request
      Powered by Jetty:// 9.4.z-SNAPSHOT

       

      The result of this error is due to CSRF protection in Jenkins 2.x.  The current workaround is for a user to complete the following steps:

      • Visit /configureSecurity page
      • Disable Prevent Cross Site Request Forgery exploits ** temporarily
      • Visit /configure upload the image desired
