look for this code here
<!-- BOF: Display grid of available sub-categories, if any -->
<?php
if (PRODUCT_LIST_CATEGORY_ROW_STATUS == 0) {
// do nothing
} else {
// display subcategories
/**
* require the code to display the sub-categories-grid, if any exist
*/
require($template->get_template_dir('tpl_modules_category_row.php',DIR_WS_TEMPLATE, $current_page_base,'templates'). '/tpl_modules_category_row.php');
}
?>
<!-- EOF: Display grid of available sub-categories -->
that should be in
/includes/templates/Slovak_Classic/templates/tpl_index_categories.php
the chances are that code isnt there in your file, hence why its not showing the subcategories, why that bit of code would have been removed is anybodys guess
if the code is there, then there must be a problem with it, its been altered and bits have been left out,
if your template doesnt have a tpl_index_categories.php file then it'll be the file in /includes/templates/template_default/templates/ thats getting used.
or
if the above file is fine, check /includes/templates/Slovak_Classic/templates/tpl_modules_category_row.php
it should look like this
require(DIR_WS_MODULES . zen_get_module_directory('category_row.php'));
require($template->get_template_dir('tpl_columnar_display.php',DIR_WS_TEMPLATE, $current_page_base,'common'). '/tpl_columnar_display.php');
if that code is missing or not written properly, it can cause the subcategories to disappear
if those files are fine, then I'd need a look through your site to see what has been done and what isnt working, guessing at where the problem really isnt the best way to do things, I'd need to have a look, but working on other people sites is never done for free
edit to add,
just checked your source code
<!-- BOF: Display grid of available sub-categories, if any -->
<!-- EOF: Display grid of available sub-categories -->
theres no code inbetween the begining of and the end of your subcategory display code, so the first code I put up should be in there, so it definetly is /includes/templates/Slovak_Classic/templates/tpl_index_categories.php thats got the problems
why did you remove the code??
