Tell us what you are trying to do?
I am reopening this ticket: https://toolset.com/forums/topic/adding-multiple-relationship-filters-to-a-view/

In the example given, this works, but it's not seeming to work for my site. Here's a more specific example.

We have a hierarchical post type called Departments. For example:
Department 1
- Department 1.1
- Department 1.2
Department 2
- Department 2.1
- Department 2.2
- Department 2.3
Department 3
- Department 3.1
- Department 3.2

We also have a post type called Special Collections, which can be in a one (department) to many (special collections) relationship with Departments.

What I would like to do is build a view that allows me to display special collections from ONLY departments 2 and 3 and their child departments (in this example, excluding any special collections associated with department 1).

When I attempt to build the view described in the original ticket, I create a view using the classic editor, replicate all settings, and try to save the view, I get an error (screenshots attached - demo site and my site are labeled in the file names).

Can you help me figure out what is causing the error here?

Hello there,

Thanks for your return!

I would like to request temporary access (wp-admin and FTP) to your site to take better look at the issue. You will find the needed fields for this below the comment area when you log in to leave your next reply. The information you will enter is private which means only you and I can see and have access to it.

Our Debugging Procedures

I will be checking various settings in the backend to see if the issue can be resolved. Although I won't be making changes that affect the live site, it is still good practice to backup the site before providing us access. In the event that we do need to debug the site further, I will duplicate the site and work in a separate, local development environment to avoid affecting the live site.

Privacy and Security Policy

We have strict policies regarding privacy and access to your information. Please see:

**IMPORTANT**

- Please make a backup of site files and database before providing us access.
- If you do not see the wp-admin/FTP fields this means your post & website login details will be made PUBLIC. DO NOT post your website details unless you see the required wp-admin/FTP fields. If you do not, please ask me to enable the private box. The private box looks like this: hidden link

Please, let me know if you need any additional details. Have a nice day.
