La verdad es que así sin ver el foro online para verle el código fuente, tampoco sabría decirte como solucionarlo. Pero tiene que ser cosa del CSS.

Si adjunto todo el código fuente serviría de algo?

Edit:
Estuve revisando el CSS que corresponde al área afectada y es una clase la que se usa la cual es "smalltext" la revisé y el color es #000 por lo que debería de aparecer en negro...

Intenta cambiar esto:

.trow1 {
        color: #000;
    background: #f5f5f5;
}

.trow2 {
    background: #EFEFEF;
}

Por esto:

.trow1 {
        color: #000;
    background: #f5f5f5;
}

.trow2 {
        color: #000;
    background: #EFEFEF;
}

En tu global.css

Ya lo solucione, Gracias! Pronto vendré con otras dudas ya que estoy modificando el tema, jaja.
