Any help with this would be appreciated.

No need to log it just yet, I cannot reproduce, I just exported a template from the default parent portal and created a child portal out of it.

So we need more info here... is this a virgin install or upgrade?

Any third party modules involved (page blaster?).

Are you exporting from a parent or child portal (it shouldn't matter but checking anyway).

This happens when you hit the export button?

Also, I've seen this problem regardless of whether I check "Include Content" or not.
