Strange one this.
Main Index - FordMondeo.org Product Reviews is the address of my RP install.
A few members are reporting back that it's working fine, ie, full skin integration from FusionBB. Yet the majority are reporting that it isn't integrating, attached are two screenshots. There doesn't seem to be any correlation either of browsers, OS'es, usergroups, it really is random.
It works perfectly for me though!
