Let me give some more information  - maybe I just don't understand how force.com sites work. Do you have to authenticate someone to let them see data from salesforce? It seems unlikely, as one page works just fine and shows me data. Here is the code for a page that does not work in force.com sites (guest users), but works perfectly otherwise. (For authenticated users). When users go to this page they should see a list of accounts. I have enabled the vf page and the controller for the guest user. As well as permissions to read accounts, and view all fields. The debug log shows no errors. It seems like a permission issue - but I just cannot imagine what I am missing. There is one other pge that does not work either, it references many more objects (related to account - opps, cases, contacts, etc. but I thought I would start with getting help with this page and hopefully learn something I can apply to the other.  Any help is appreciated. 

Controller:

public with sharing class AccountSearchController {

  // the soql without the order and limit
  private String soql {get;set;}
  // the collection of accounts to display
  public List<Account> accounts {get;set;}
 
  // the current sort direction. defaults to asc
  public String sortDir {
    get  { if (sortDir == null) {  sortDir = 'asc'; } return sortDir;  }
    set;
  }
 
  // the current field to sort by. defaults to account name	
  public String sortField {
    get  { if (sortField == null) {sortField = 'Name'; } return sortField;  }
    set;
  }
 
  // format the soql for display on the visualforce page
