Solved 500 Error - Fatal Error: Class 'CKunenaLink'

Buenas tardes a todos,

Tengo un foro con kunena 3.0.1 que a priori no daba ningún problema. Hoy un usuario me ha comentado que no podía cambiar su cofiguración y efectivamente al pinchar en "Editar perfil" me salta:

Fatal Error: Class 'CKunenaLink' not found in components/com_kunena/template/blue_eagle/html/user/edit_avatar.php on line 54

Es en el único lugar donde encuentro el error. Encuentro algunas referencias a este error, pero solo en temas en alemán.
