Fix for PI frontend category/section select from url

From forum here:
http://www.pages-and-items.com/index.php?option=com_kunena&Itemid=29&func=view&id=2136&catid=8#2136

url format:
[code]index.php?option=com_pi_pages_and_items&task=item&sub_task=new&pageId=888&item_type=custom_3&Itemid=63&section=1&category=40&hide_select=1[/code]


version 1.4.6
file:
administrator/components/com_pi_pages_and_items/admin/item.php
line: 55
[code]//check section access. don't check if from frontend, sections and category select will be filtered out
    if(!$class_pi->check_section_access_by_pageid($page_id) && !$frontend){
      
   [/code]

change to
[code]    //check section access. don't check if from frontend, sections and category select will be filtered out
    if(!$frontend){
        if(!$class_pi->check_section_access_by_pageid($page_id)){
          
   [/code]

and add a } to close the extra if().
