Whenever I try to add or edit a subpage (i.e. a child page of a main page), I am getting this error:
Full error is: count(): Parameter must be an array or an object that implements Countable.
Offending line is: <div data-grav-array-type="container">
This is happening in: /grav/templates/forms/fields/array/array.html.twig.
I'm not familiar enough with Grav to understand the stack and debug it. Thanks for any help.
