SOLUCIONADO
Bueno, por si a alguien más le vuelve a pasar... finalmente he conseguido arreglarlo. He activado el modo DEBUG como se indica aquí:
Habilitar el modo DEBUG
y me salían estos errores:

buscando en google, he encontrado este post, donde les pasaba algo similar tras haber actualizado a la versión 3.011:
https://www.phpbb.com/community/viewtopic.php?t=2162681
Yo no he actualizado nada, PERO, ahí hablaban de que habían estado borrando usuarios de spam y el problema quizá era debido a que, por error, se había eliminado el usuario anónimo. Hace como 2 semanas estuve borrando usuarios caca, y quizá ahí me lo cargué sin querer...
He probado a ejecutar esto en phpmyadmin y ARREGLADO

Os lo dejo por aquí por si a alguien le vuelve a pasar próximamente...
