Magento Edit Category Issue In Admin After Updating

Hi Friend's

When you update magento version and everything is working fine and as expected but the catalog/category. when you not able to edit/delete categories from Admin Panel and check your ajax request in console.

The Console details are as follow:

URL being hit each time I click on category name:
http://my-domain.com/index.php/admin/catalog_category/edit/key/<magento_scurity_key(EX.1ac1f1e5f75e665a2fd06eca4569d662)>/?admin%2Fcatalog_category%2Findex%2Fkey%2F1ed297c236a0c9df5530952aaf7e0618%2F=id/7/&isAjax=true

Get Params:

isAjax : true

q : index.php/admin/catalog_category/index/key/bdf7b2cc9b890b6cb7e687a31bc7c35c/id/7/

POST Params:

active_tab_id : category_info_tabs_group_4

form_key : FeUR7dFe2MutCtcB


And This always bring a blank category form.

Solution:

Copy /app/code/core/Mage/Core/Model/Url.php

to /app/code/local/Mage/Core/Model/Url.php

an change line number around 1016 in magento 1.9 another search "if ($query)"

if ($query) {
    $mark = (strpos($url, '?') === false) ? '?' : ($escapeQuery ? '&amp;' : '&');
    $url .= $mark . $query;
}
To replace
//if ($query) {
if ($query && strpos($query, 'catalog_category') === false ) {
    $mark = (strpos($url, '?') === false) ? '?' : ($escapeQuery ? '&amp;' : '&');
    $url .= $mark . $query;
}

Now Flush Magento Cache and refresh page

Hope this information is helpful to you :)
