When I clicked on a link (probably a partial link) in a news feed item that was a preview(?) of an answer to a Question that had been asked, I received the following error:

Fatal error: Uncaught Error: Call to undefined method forums::vi() in /home/laserev1/link/index.php:48 Stack trace: #0 {main} thrown in /home/laserev1/link/index.php on line 48

Added:

• x081 Questions: Preview text in from questions show in newsfeed truncate links causing them to break
  (added note: Integrate solution with ticket #017 Questions: previews stop at an arbitrary number of characters)
