Sorry , I wasn’t clear enough.
In my case, I had to edit a simple product, to a variable one, uncheck once I am editing in variable the “Used for variations” setting , then go back to simple product, and save again, as a simple product, then all the attributes display.
Because of course you can’t have a variable product with no variations…
Thank you again for your plugin and support, excellent, I really appreciate.
Got it. I need to change my product to variable product and not single product, and now it will be display.
I am pretty sure it was displaying before for simple product, which in my case still have attributes that needed to be displayed.
I will look for all the simple product and edit them to make them into aribale product in wordpress then.
