Pludselig fejl i kode ?!?

Jeg får en underig fejl i en kode der hidtil har virket perfekt. Er der nogen der ud fra filerne herunder, kan udlede hvad og hvor fejlen er, samt rette den for mig ?!?

Fejlen:

Systemet har virket upåklageligt indtil det seneste server skift..
Systemet kan ses i aktion her http://anakin.dk/mayday/ og fejlen opstår når der klikkes på linkene..

Jeg giver ikke point for opgavens størrelse, men for hjælpen der ydes..
