Error on full width export

Hello,

I’m having problmens in exporting a full width site after the last update on Simply Static. Before that, it was all working fine.
You can see the difference on the links below:
1) this is the WordPress source:
http://templates.cipnet.com.br/primusgraf/

2) this is the exported html:
http://www.primusgraf.net.br/

I’ll look forward to hear from you as soon as possible.

Regards,
Marcelo
