Problem with font-weight: bold throughout the forum

Ciao a tutti e scusate per l'inglese.
Non so per quale motivo ma ho il grassetto su tutte la pagine del forum, da pannello di controllo non ho trovato nulla mentre con firebug ho trovato questo codice
Come posso risolvere? Grazie

Or speak to the style designer.
