Hi
 List Seller Items plugin default url is http://maindomain.com/search/seller_post,1/iPage (where 1=user ID)

/search/ segment of url is a part of permalink and it can be changed/customised via OSClass backend/permalinks scheme menu.

If /search/ part of permalink is edited to anything other than default (i.e. to /found/ or to any other value), seller all items link stops working (404) because it still points to default url with /search/ instead to rewriten permalink http://maindomain.com/found/seller_post,1/iPage.

You can change this in file:
/oc-content/plugins/list_seller_items/index.php

On line:
$url = osc_base_url() . 'search/seller_post,' . osc_item_user_id() . '/iPage';

Thanks, it should not be hardcoded but its better than 404 :-).

In original plugin version there was no friendly url version and this is better than non-friendly
