From what I understand is that he gets all the subdomains

SELECT t.*, tt.* FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON t.term_id = tt.term_id WHERE tt.taxonomy = 'category' AND t.term_id = 4 LIMIT 1
                  134 Query     SELECT * FROM wp_category_subdomains WHERE cat_ID = 4

This works ok

Next he calls

SELECT DISTINCT posts.ID FROM wp_posts posts JOIN wp_term_relationships ON posts.ID = wp_term_relationships.object_id JOIN wp_term_taxonomy ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id WHERE wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id in (12) AND posts.post_type != 'page' AND posts.post_status = 'publish'

which is the actual posts of the category which is in $wps_this_subdomain

But I don’t understand why he next calls the posts for the other categories also. Which of course results in all posts.

Hope this helps a bit?

Do you see category lists in settings page?

Not exactly sure what you mean by this.

All subdomain-enabled -> yes

I checked and $wps_this_subdomain is actually containing the right domain but for somehow he doesn’t filter out the messages which are not belonging to the right category. I logged below the sql queries and below is the result of a category page.

@lontongcorp I have the same issue as zechmann. All categories are being redirected to my main page instead of applying the category filter
