CATEGORIES' items won't be displayed

my settings are as follows:
serverOS: Linux 2.6.9-42.0.3.ELsmp MySQL 4.1.22-standard
PHP 4.4.1
Zen Cart 1.3.0.2-l10n-jp-2

I just upgraded form Zen Cart 1.２.1.
this problem persisted from before, though when i open the top page, photos for the categories will show up, but when I click the categories picture to see the items in the categories, the items will not show up.
only the new items from this month box show up and there are no categories items showing up.
when I registered the item photographs in the first place, i did not upload to the categories folder, so i tried to upload there but the things won't change.

I thought maybe some of the files are missing but I checked everywhere i can think of, however i did not find the file below in the admin and shop.
i wonder if I need to obtain that file for my version of the zencart or not.
if so how can i obtain it..

includes/classes/categories_all_products.php
also i do not find any file that said
tpl_index_category_row.php
on include/templates/templates default/templates
where i used to have the file when i was using the Zen Cart 1.２.1.
so i decided to upload the file and then there was a error message.

also i checked following files and they are uploaded
include/modules/product_listing.php
admin/include/modules/category_product_listing.php
include/template/tpl_modules_product_listing.php

I looked on the contents of the
category_product_listing.php
and wondered some of the setting where it said "0" is fine as it is or not..
please see below.
i asked ppl, but it seems nobody can not find out the answer.
thank you appreciate your help..

if (isset($_GET['set_display_categories_dropdown'])) {
$_SESSION['display_categories_dropdown'] = $_GET['set_display_categories_dropdown'];
}
if (!isset($_SESSION['display_categories_dropdown'])) {
$_SESSION['display_categories_dropdown'] = 0;
}
?>

First if you are upgrading at this time from 1.2.x to 1.3.x - Why are you not using 1.3.8a?

From 1.2.x to 1.3.x there are several differences in files and these can be determined from the changelog file in the documents folder.

If you are attempting to utilize a 1.2.x template this is most likely your problem.

hello sir thank you for quick reply,
no actually that is the most latest version of zen cart for japanese version,
and I am not using template from 1.2.
i just thought that one file, tpl_index_category_row.php was missing from the 1.3 and thought of importing that file, but maybe it is not necessary.

I needed all the zencart to be written out in Japanese because most of jp ppl won't read English, so I am using Jp zencart and making it bilingual.

i know most cases to have blank page like this would be just because some files are missing at the time or uploading or upgrading.

but so far i checked every file uploaded correctly.

it is just some <table border="0" width="100%" cellspacing="0" cellpadding="2">

code i notice from the source code and those "0" setting need to change to numbers? but what file I need to edit, for which amount, I would like to know,
if that was the case, if you can think of any files within this version i really appreciate it..
thank you sir...

Statements for this are correct:

<table width="100%" border="0" cellspacing="0" cellpadding="0" id="contentMainWrapper">

thank you...

and also I changed the setting on product listing in the configuration in admin .
some of the numbers there were 0!!so i changed to number. but
now it only showed up some grids and then quantity, but the images won't show up.
but it seems like the key is there, some setting number might be wrong.
anybody can solve??

i do not understand the meaning of this sentence to. what stands for 2a??:
Sort the Product Listing in the order you wish for the default display to start in to get the sort order setting. Example: 2a
i set it as just 2a.. maybe this is where the key is..

anyone can find out,, thank you so much...

i do not understand the meaning of this sentence to. what stands for 2a??:
=position in sort of #2
a= accending

actually now i solved...
it was just the character setting was different for the numbers (it has to be half sized number in jp font )
and it was the numbers used for the product listing in the configuration as i suspected.
thank you so much .
