Problem with plugin capa and job manager

I have a problem with the Job Manager plugin

The job manager plugin creates a page that is located here: http://futbolpf.com/2012/?page_id=90

The problem is that when trying to enter any of the job shows me permission denied when accessing the page of the offer is this: http://futbolpf.com/2012/?page_id=91&j=348

The page with id 91 does not exist, the plugin creates the job manager, the main page with id 90 if there actually, so I’ve been able to apply the permissions to the plugin CAPA

but as I apply permissions to the page with id 91 if it does not exist?

Thanks and excuse my language
