Okay no problem
One big issue I see is this. Basically on install it looks like you had not put the proper table prefix for
vb so your usergroups where not inputted into our usergroups table. You can use phpmyadmin and view the photopost pp_usergroups table and add an entry named Administrators with a groupoid of 6 and cpaccess set to 1 this will give you admin access to photopost.
