[Resolved] Custom post query

Problem:
You have a custom plugin with a custom post type. When the site's current language is set to a non-default language, such as Dutch, and you create a custom post type, it is only associated with the current language. You tried using

'lang' => 'all'

in WP_Query parameters without success. The issue is that when performing a WP_Query for the custom post type, only records in the default language are shown, filtering out records in other languages.
Solution:
To include custom post types in all languages in your WP_Query, you need to use the

suppress_filters

argument in your query. Here's how you can modify your WP_Query:
1. Set

suppress_filters = true

to fetch posts from all languages.
2. Set

suppress_filters = false

to get posts only in the currently viewed language.
