I am trying to:
Edite child posts in a many to many relationship
Link to a page where the issue can be seen:
Only visible in admin
I expected to see:
Child posts to be editable regardless of the number of parents
Instead, I got:
In this scenario I have an accessory custom post type that is the child of a products post type (not woo) This accessory applies to a couple of dozen products. When the child only has a few parents it is editable fine, (Image A) but above a certain number, it becomes editable and displays thus, Image B
The child post only lose editability after being connected to a number of parents
That will create a debug.log file in your /wp-content/ directory which you can examine in any text editor. Try editing an accessory with many parents where it does not work and then inspect the log. If you don't find the debug.log file it means it didn't generate any warnings or errors.
If there are no warnings or errors, could you try disabling all non-Toolset plugins and switching theme to twentyseventeen and testing again. If it then works you should be able to identify the source of any conflict by a process of elimination.
