I have already created relationships between different post types and I expected to see the relationship form in the backend but I did not see it. Furthermore when I tried to add a new relationship form, the create new button is disabled.
I tried to replicate the problem on another site in the same network but for some reason everything is working on the other site.
I've already tried to clear the cache in my browser as well as use different browsers. I've also tried to deactivate all plugins which are not required.
Actually the problem here is that its not a many to many relationships. Many to Many relationships are handled differently and they require the use of the relationship form.
However with your setup you will create a regular Form to perform this.
I've tried to create a one to one, one to many and many to many relationship type, and for my test site, all of them are working, and the boxes for the relationship show up in the backend. However for the mainsite the boxes in the backend is simply not showing up even after I've checked SCreen Options to make sure that everything is showing.
From your screenshot I see that the relationship feature is working fine. So you're saying on this site the relationship boxes show up fine ?
However on your Main site they don't ?
Could you temporarily disable all the non-toolset plugin on the main site and check again to see if the boxes show up ?
I tried disabling all non toolset plugins on the main site but the relationship forms didnt show up. Decided to do a manual migration to the new site using Modules
I previously closed the support ticket because the relationships function was working on my new wordpress installation. But then the frustrating thing is that it suddenly stopped working and now I am back to square one. I do not know what caused the relationship functionality to suddenly not work. I already tried disabling plugins but that didnt seem to help. What changed was that I was adding in some Custom Post Types and then suddenly this function is disabled.

Just to clarify: The existing relationships are still there but I am unable to edit it from the back end and I am unable to create front end forms to edit it from the front end.
