Hi Armen,
That sounds you like you probably just need to flush your permalinks, something that is often necessary when new custom post types are registered in WordPress or changes are made to custom post types. To do this:
– In the main menu, go to “Settings > Permalinks”.
– Scroll down, if needed, and click “Save Changes”. No need to actually make any changes.
– Rewrite rules and permalinks have now been flushed.
