lots of pages not showing

[All_That_Chaz]

token list, profile vote page, lvlrank, regional leaderboards, etc not showing.

Below the list of mirrors on the left side of the page, another bubble also labeled "FFR mirrors" is there. This is also on the home page but doesn't cause an error. On the above mentioned pages, inside the second mirror bubble is just this error message:
Fatal error: Call to undefined function feedlist() in /home/virtual/site1/fst/var/www/html/wp-content/themes/FFR Theme/leftsidebar.php on line 325
