I am trying to: Use a Front-end Form to edit existing / add new. Connected posts do not show up on the edit form, if any changes are made using that form existing connections are removed
Hello,
I assume we are talking about the Toolset post form "Edit House & Land Package", and field "home-design_house-and-land" in it.
I have test it in here:
hidden link
Click button "Edit", I can see the post form, and there are already lots of existed JS errors in your website, for example:
wp-playlist.min.js?ver=5.1.1:1 Uncaught ReferenceError: Backbone is not defined
utils.js?ver=1.2.2:11 Uncaught ReferenceError: Backbone is not defined
frontend.js?ver=2.3.1:367 Uncaught ReferenceError: ko is not defined
Uncaught TypeError: Cannot read property 'setDefaults' of undefined
See screenshot js-errors.JPG
Since the relationship field is using JavaScript select2, those errors will prevent it from working.
I suggest you check these:
1) In case it is a compatibility problem, please deactivate other plugins, and switch to wordpress default theme 2019, also remove other custom PHP/JS codes, and test again
2) if the problem is fixed, you can locate the problem plugin by activate them one by one.
