Android: Couldn't read row 0, col -1 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it

When executing a getter method to pull DB data into a GridView I get the following error:

Caused by: java.lang.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow.  Make sure the Cursor is initialized correctly before accessing data from it.

DBHelper class;

public List<Site> getAllSites(){
    List<Site> sites = new ArrayList<Site>();
    String selectQuery = "SELECT * FROM " + TABLE_SITES;

    Log.e(LOG, selectQuery);

    SQLiteDatabase database = this.getReadableDatabase();
    Cursor c = database.rawQuery(selectQuery, null);

    if (c.moveToFirst()){
        do {
            Site st = new Site();
            st.setSiteID(c.getInt(c.getColumnIndex(KEY_SITE_ID))); //Error thrown here
            st.setSiteName(c.getString(c.getColumnIndex(KEY_SITE_NAME)));
            st.setSiteLat(c.getDouble(c.getColumnIndex(KEY_SITE_LAT)));
            st.setSiteLon(c.getDouble(c.getColumnIndex(KEY_SITE_LON)));
            st.setSiteCreatedDateTime(c.getString(c.getColumnIndex(KEY_CREATED_AT)));

            sites.add(st);
        } while (c.moveToNext());
    }
    return sites;

}

The error is thrown at:

siteList = db.getAllSites(); in MainActivity and at

st.setSiteID(c.getInt(c.getColumnIndex(KEY_SITE_ID))); in DBHelper class
